Question

Let f(x) = x + 8 and g(x) = x - 4. What is f(x) • g(x)? Help please

Answer 1

assuming that's a multiplication symbol, you just multiply the two functions

Answer 2

f(x) * g(x) = (x+8)*(x-4)


f(x) * g(x) = x*(x-4) + 8*(x-4) ... use the distributive property


f(x) * g(x) = x*x-x*4 + 8*x-8*4 ... use the distributive property again


f(x) * g(x) = x^2 - 4x + 8x - 32


f(x) * g(x) = x^2 + 4x - 32

Answer 3

hopefully that makes sense

Answer 4

do you still need help?
