Question

WHat is the y- intercept of the quadratic function f(x)=(x-6)(x-2)?

Answer 1

I think it's (0, -12)

Answer 2

The y-intercept of the quadratic function f(x) is 12.

Explanation:

The given function is

`f(x)=(x-6)(x-2)`

At y-axis the value of x is 0.

Substitute x=0 in the given function to find the y-intercept of the function.

`f(0)=(0-6)(0-2)`

On simplification, we get

`f(0)=(-6)(-2)`

`f(0)=12`

The graph of function intersect y-axis at (0,12).

Therefore the y-intercept of the quadratic function f(x) is 12.
