ANSWER

The y-intercept is (0,-11)

The x-intercepts are:

(-1,0) and (11,0)

Step-by-step explanation

The given function is


f(x) = {x}^(2) - 10x - 11

To find the y-intercept, we put x=0 into the function.


f(0) = {0}^(2) - 10(0) - 11


f(0) = - 11

The y-intercept is (0,-11)

To find the x-intercepts, we put f(x)=0.


{x}^(2) - 10x - 11 = 0


(x + 1)(x - 11) = 0

This implies that,


x = - 1 \: or \: x = 11

The x-intercepts are:

(-1,0) and (11,0)
