Question

Consider the functions f(x) = 3x − 2 and g(x) = x2 − 1. What is the value of f[g(5)]?

Answer 1

first evaluate g(5) = 5^2 -1 =25-1 =24
then evaluate f(g(5)) = f(24) = 3*24-2 =70

Answer 2

i dont get it

Answer 3

can u make it simpler

Answer 4

they are asking you to evaluate f(x) =3x-2 but they want x to be the vaule which is equal to g(5)

Answer 5

soo 3x(5) -2

right

Answer 6

which is 13

Answer 7

x= g(5) = 5^2 -1 =24
f(24) = 3*24- 2 = 70

Answer 8

the answer should be 70

Answer 9

soo then wat do u do

Answer 10

f(g(5)) is not a multiplication is a comp function

Answer 11

can u show me step by step

Answer 12

how did u get 70

Answer 13

sorry I am having prob with the internet

Answer 14

Let see first what is given ;
f(x) = 3x-2 , g(x) = x^2 -1

they are asking to find f(g(5)) =?
this means that you need to first evaluate g(x) =x^2-1 when x =5
that is g(5) = 5^2 -1 =25-1=24
because g(5) =24 this values is the one that need to plug in f(x)
that is f(g(5) = f(24) = 3*24-2 =72-2=70
