Ka quadratic function f (x) is hidden from view. you must find the y-intercept(s) of f(x) and write the answer(s) in the form (x, y). choose the form of the quadratic function f (x) that you would like to see in order to answer the question most effectively.

step-by-step explanation :

we know that

the measurement of the outer angle is the semi-difference of the arcs which comprises

in this problem

m< xzy is the outer angle

substitute the values

the measure of angle xoy is equal to

> by central angle

substitute the value

m=-16
