Question

Use the equation: ……e. Find the y-intercept. If there is none, write “n/a.”(I only need help with option E)

Answer 1

The function is

$h(x)=\frac{x+7}{x^2-49}$

The y-intercept is the point such that x=0.

In our case:

$\begin{gathered} h(0)=\frac{0+7}{0-49}=-\frac{1}{7} \\ \Rightarrow h(0)=-\frac{1}{7} \\ \Rightarrow(0,-\frac{1}{7}) \end{gathered}$

The answer is the point (0,-1/7), or h(0)= -1/7
