f(x)=(x-8)(x+3)
f(x)=x^2 - 8x + 3x - 24
y-intercept when x = 0 so then f(x) = -24

answer
y-intercept (0, -24)

The curve passes through y-axis at [tex]x=0[/tex]

Substituting [tex]x=0[/tex] into [tex]f(x) = (x-8)(x+3)[/tex] we have:

[tex]f(0) = (0-8)(0+3)[/tex]
[tex]f(0)=(-8)(3)[/tex]
[tex]f(0)=-24[/tex]

The y-intercept is -24
