Question

If f(x) = 3x - 4 and g(x) = x^2, find the value of f(3) - g(2)

Answer 1

F(3) -g(2) = 1

Explanation:

F(3)= 3(3) -4= 5

g(2)=
`2^(2)` = 4

f(3) -g(2)= 5-4 =1

Answer 2

`\huge\boxed{\sf 1}`

Explanation:

Given functions:

f(x) = 3x - 4

Put x = 3

f(3) = 3(3) - 4

f(3) = 9 - 4

f(3) = 5 ------------------(1)

Also,

g(x) = x²

Put x = 2

g(2) = (2)²

g(2) = 4 --------------(2)

Subtract Eq. (2) from Eq. (1)

f(3) - g(2):

= 5 - 4

= 1
