F(×)=-3x+7, what is the value of f(1) f(-8)

Use the substitution method

f(x)= -3x+7

f(1)= -3(1)+7

= -3+7

= -4

f(-8)= -3(8)+7

= -24+7

= -17

Answers :

f(1)= -4 , f(-8)= -17

7.25

step-by-step explanation:

we know that 7 equals to 7.0. we also know that 1/4=0.25. so we can add the two together and we get 7.25

hello from mrbilldoesmath!

answer:   x (x+6)^2, choice b

discussion:

factor x out of the equation:

x^3 + 12x^2 + 36x = x (x^2 + 12x + 36).

note that 6+6 = 12 and 6*6 = 36 so the above factors into:

x (x+6)^2

which is choice b
