Question

Given the functions f(x) = 10x + 25 and g(x) = x + 8, which of the following functions represents f[g(x)] correctly?

A)f[g(x)] = 10x + 33
B)f[g(x)] = 10x2 + 33
C)f[g(x)] = 10x + 105
D)f[g(x)] = 10x2 + 105

Answer 1

Answer 2

to find f((g)x)0 replace the x in f(x) by g(x) and simplify

Answer 3

this is
10(x + 8) + 25
- now simplify

Answer 4

WAIT

Answer 5

105?

Answer 6

10x + 105

Answer 7

115

Answer 8

115?

no you cannot add 10x and 105 because they are different terms

10 oranges plus 105 apples = 10 oranges + 105 apples NOt 115 oranges or 115 apples

Answer 9

the correct option is 10x + 105
