F(x) = -8 (5-x), what is the value of f(-4)?

f(-4) is basically just saying that you need to use the function given while x = -4.

The function given:

f(x) = -8(5-x)

We see that f(-4) means that x has to be -4, so we can substitute it in:

f(-4) = -8(5-(-4))

f(-4) = -8(9)

f(-4) = -72

Therefore, f(-4) is -72.

i think this could be a possible answer (1 / 84) -1

good luck! : d

the answer is 31.27mph
