Answer:

The y-intercept is the point (0,-8)

see the attached figure

Step-by-step explanation:

we have

[tex]f(x)=x^{2}-2x-8[/tex]

we know that

The y-intercept is the value of the function f(x) when the value of x is equal to zero

so

For x=0

[tex]f(x)=0^{2}-2(0)-8\\f(x)=-8[/tex]

therefore

The y-intercept is the point (0,-8)
