Prehistoric cave paintings were discovered in a cave in France. The paint contained \( 38 \% \) of the original carbon-14. Use the exponential decay model for carbon-14, \( A=A_{0} e^{-0.000121 t} \) to estimate the age of the paintings. The paintings are approximately \( \square \) years old. (Round to the nearest integer.)

Question 7 (1 point) State the equation of \( f(x) \) if its domain is \( \{x \in R \mid x \neq 0\} \), the \( y \)-intercept does not exist, and the equation of the horizontal asymptote is \( y=1 \).

State the equation of \( f(x) \) if its domain is \( \{x \in R \mid x \neq 0\} \), the \( y \)-intercept does not exist, and the equation of the horizontal asymptote is \( y=1 \).

What is the range of \( y=-5 \sin (x) \) ? all real numbers \( -5 \leq y \leq 5 \) all real numbers \( -\frac{5}{2} \leq y \leq \frac{5}{2} \) all real numbers \( -1 \leq y \leq 1 \) all real numbers \( -\frac{1}{5} \leq y \leq \frac{1}{5} \)
