Answer:
The y-intercept of the quadratic function f(x) is 12.
Step-by-step explanation:
The given function is
[tex]f(x)=(x-6)(x-2)[/tex]
At y-axis the value of x is 0.
Substitute x=0 in the given function to find the y-intercept of the function.
[tex]f(0)=(0-6)(0-2)[/tex]
On simplification, we get
[tex]f(0)=(-6)(-2)[/tex]
[tex]f(0)=12[/tex]
The graph of function intersect y-axis at (0,12).
Therefore the y-intercept of the quadratic function f(x) is 12.
