Answer:
4 + 14b
Step-by-step explanation:
First, you need to distribute so,
2*2= 4 and
2*7b= 14b
To find f(1), substitute 1 for x.
f(1) = (3(1)+7)²
f(1) = (3+7)²
f(1) = 10²
f(1) = 100
I do believe that that point is -2.2 because of the fact that the difference between -1.6 and -2.4 is 0.8, and there are 4 marks in between them. So each mark's value is decreased by -0.2.
The ratio of the surface area to the volume will decrease
