HELP ME

Answer 1

Given the following functions f(x) and g(x), solve f[g(10)] and select the correct answer below:

f(x) = 10x + 8

g(x) = x + 9

2,052
98
190
198

Answer 2

Replace x in f(x) by x+9

Answer 3

Then you can simply plug in value to get f(g(x))

Answer 4

is it b

Answer 5

just like what @AravindaG said but i will clearify more.

f(x) = 10x + 8
g(x) = x+9
substuitue x+9 instead of x in f(x)
f(x+9)= 10(x+9) + 8
f(x+9) = 10x+ 90 + 8
f(x+9) = 10x+98
Now find substitue x=10 to find the number you looking for.
f(10+9)= 10(10) + 98
f(10+9)= 198
