A function f(x) has x-intercepts of -3 and -5. What is the constant term in the function? F(x)=x2+8x+

15

Step-by-step explanation:

If -3 and -5 are the x intercepts, then (x+3) and (x+5) are factors

f(x) = (x+3)(x+5)

Expand

f(x) = x² + 5x + 3x + 3(5)

f(x) = x²+8x + 15

Equate x²+8x + 15 with x²+8x

x²+8x + 15 = x²+8x + b

On comparing

15 = b

Swap sides

b = 15

Hence the constant term is 15
