Answer:
Foil the expression and solve the derivative with respect to b at f'(x)=0
Step-by-step explanation:
Hello :
f(-4) = 4(-4)+9 = -7
f(-2) = 4(-2)+9 = 1
f(0) = 4(0)+9 = 9
f(2) = 4(2)+9 = 17
the range of the function f(x) = 4x + 9 is : <span>D' = {-7, 1, 9, 17}</span>
Less that sigh if it it pointing to the left if it is to the right grater than
