y-intercept: value of the function when it crosses y-axis (when x=0)
x-intercept: values of x when the function cross the x-axis (when the function is equal to 0)

To fidn y-intercept evaluate the function when x=0 (find f(0)):

y-intercept: 100
To find x-intercepts; equal the function to 0 and solve x:

Factor by parts:

Solve x: When the product is 0, equal each factor to 0 and solve separately:
![\begin{gathered} x^2-25=0 \\ x^2=25 \\ x=\sqrt[]{25} \\ x=\pm5 \\ \\ \\ x-4=0 \\ x=4 \end{gathered}](https://img.qammunity.org/2023/formulas/mathematics/college/f7rsq2clwraiscnw6t1vmr1me2e2n66m7f.png)
