Answer:

The y-intercept of f(x) is -24.

(0,-24)  C is correct.

Step-by-step explanation:

Given: [tex]f(x)=(x-8)(x+3)[/tex]

We need to find the value of y-intercept.

For y-intercept, put x=0 into f(x) and solve for y because it lie on y-axis.

Put x=0 into f(x)

[tex]y-intercept=f(0)[/tex]

[tex]f(0)=(0-8)(0+3)[/tex]

[tex]f(0)=-24[/tex]

y-intercept: (0,-24)

Hence, The y-intercept of f(x) is -24.
