Answer

(a) The graph of \( f(x) = |x| \) is a V-shape with its vertex at (0,0). (b) Domain of \( f \): All real numbers, \( (-\infty, \infty) \). (c) Range of \( f \): \( [0, \infty) \). (d) Intervals on which \( f \) is increasing: \( [0, \infty) \). (e) Intervals on which \( f \) is decreasing: \( (-\infty, 0] \). (f) Intervals on which \( f \) is constant: None. (g) Distinct \( y \)-values of relative maximums: None. (h) Distinct \( y \)-values of relative minimums: 0. (i) \( y \)-value of the absolute maximum: Does not exist. (j) \( y \)-value of the absolute minimum: 0.

Solution

We are given the function   f(x) = |x – 0| = |x|. Its graph is the familiar V–shape with its vertex at (0, 0). (The “letter” that corresponds to the graph depends on the multiple–choice diagram provided; the correct answer is whichever one shows this V–shape with vertex at the origin.) Now let’s list the answers one by one: (a) Letter that corresponds to the graph of f:   Answer: The letter corresponding to the V–shaped graph with vertex (0,0). (That is, whichever diagram shows a V–shaped graph symmetric about the y–axis.) (b) Domain of f:   Answer: (–∞, ∞). (c) Range of f:   Answer: [0, ∞). (d) Intervals on which f is increasing:   Answer: f is increasing on [0, ∞); that is, as x increases past 0, f(x) = x increases. (e) Intervals on which f is decreasing:   Answer: f is decreasing on (–∞, 0]; that is, as x increases (from –∞ up to 0) the value |x| decreases. (f) Intervals on which f is constant:   Answer: f(x) = |x| is not constant on any interval. (g) Distinct y–values of the relative maximums, if any exist:   Answer: There are no relative maximums. (h) Distinct y–values of the relative minimums, if any exist:   Answer: f has a relative (and, as we will see, absolute) minimum at y = 0. (i) y–value of the absolute maximum, if it exists:   Answer: f is unbounded above (since |x| → ∞ as |x| → ∞), so there is no absolute maximum. (j) y–value of the absolute minimum, if it exists:   Answer: The absolute minimum value is 0, attained at x = 0. Any answer that includes these results is correct.

The function \( f(x) = |x| \) is a classic V-shaped graph opening upwards with its vertex at the origin (0,0). The graph is symmetric about the y-axis and consists of two linear segments. The letter corresponding to this graph would typically be indicated in a multiple-choice format (e.g., A, B, C) based on the options provided. The domain of \( f \) includes all real numbers since you can input any value for \( x \) in the absolute value function, thus: Domain of \( f \): \( (-\infty, \infty) \). The range of \( f \) represents all possible outputs of the function, which can only be zero or positive values, leading to: Range of \( f \): \( [0, \infty) \). The function increases for values of \( x \) greater than 0 and decreases for values less than 0. This means the intervals on which \( f \) is increasing are \( (0, \infty) \) and it is decreasing on \( (-\infty, 0) \). There are no intervals on which the function is constant since it changes continuously across its domain. Relative maximums and minimums for \( f(x) \) can be analyzed from the graph. Here, there’s a relative minimum at the vertex, where \( y=0 \) at \( x=0 \). Therefore, the distinct \( y \)-values of the relative minimums is: \( 0 \). There are no relative maximums since the graph heads to infinity. For absolute maximums, since the function increases indefinitely, there is no absolute maximum value. On the flip side, the absolute minimum value is at the vertex, which is also \( 0 \). In summary: (a) \( \square \) (based on options), (b) Domain of \( f \): \( (-\infty, \infty) \), (c) Range of \( f: [0, \infty) \), (d) Intervals on which \( f \) is increasing: \( (0, \infty) \), (e) Intervals on which \( f \) is decreasing: \( (-\infty, 0) \), (f) Intervals on which \( f \) is constant: none, (g) distinct \( y \)-values of the relative maximums: none, (h) distinct \( y \)-values of the relative minimums: \( 0 \), (i) \( y \)-value of the absolute maximum: none, (j) \( y \)-value of the absolute minimum: \( 0 \).
