Form quadratic functions given the following information:
Zeroes at 4 and –2, f(0)=4

Step-by-step explanation:

we know that

A quadratic function in factored form is equal to

where

a is the leading coefficient

x_1 and x_2 are the zeroes of the function

substitute the given values

Find the value of a

Remember that

For x=0 ----> f(0)=4

substitute

so
