Find the missing numerator: \( 3 / 4=? / 24 \)

c) \( 5^{0}= \)

b) \( (-3)^{2}= \)

Consider the following function. \[ f(x)=1-x^{2 / 3} \] Find \( f(-1) \) and \( f(1) \) \( f(-1)=\square \) \( f(1)=\square \)

The retail flat rate in dollars for first-class mail weighing up to 5 ounces could be computed by the piecewise-constant function \( f \), where \( x \) is the number of ounces. (a) Evaluate \( f(1.1) \) and \( f(4) \). Interpret your results. (b) Sketch a graph of \( f \). What is the domain of \( f \) ? What is the range of \( f \) ?

c) \( \sqrt[3]{729} \cdot 4^{2}-\sqrt{49} \cdot 5^{0} \cdot 1^{3} \)
