The y-intercept is the point at which a function cuts the y-axis. It can be found by evaluating the function at x=0. The coordinates of that point will be:

(0,f(0))

Evaluate <em>f(0):</em>

\begin{gathered} f(x)=x^2+2x-15 \\ \Rightarrow f(0)=(0)^2+2(0)-15 \\ =0+0-15 \\ =-15 \end{gathered}

Since <em>f(0) = -15 </em>, then the coordinates of the y-intercept are:

(0,-15)
