Evaluate
f(x)=3^x +4 when x=2

A. 10
B. 13
C. 18
D. 36

B

Step-by-step explanation:

Substitute x = 2 into f(x) , that is

f(2) = 3² + 4 = 9 + 4 = 13

38.5

step-by-step explanation:

lets say, first number = r

second number = 3r+7

total = 49

(r)+(3r+7)= 49

4r+7 = 49

4r = 42

r = 42/4

r= 10.5

3r+7 = 3(10.5)+7 = 38.5
