find f(-4) if f(x) = 3x - 6.

a 6
b -6
c 18
d -18

f(-4) = -18

Step-by-step explanation:

f(-4)  means x = - 4

So Plug in x = - 4 into f(x) = 3x - 6

f(-4) = 3(-4) - 6

= -12 - 6

= -18

So

f(-4) = -18

a. the residual plot for model 1 has a random pattern and is a good fit for the data.

answer: since the question is talking about growth you have to use the growth formula which is inital amount (1 + growth)^time

step-by-step explanation:

the intial amount is 1200, the growth is 4.8, and the time is 7. plug those numbers into the equation, also i think you have to change 4.8 into a percent. but, i have forgotton how to do that. if this is a online class go on to the lesson.
