Question

Let f(x) = 3x + 2 and g(x) =x - 3. Find f(x) - g(x). Question 3 options: 2x - 5 4x - 1 2x - 1 2x + 5

Answer 1

Answer: f(x)-g(x)=2x+5

Step by step:

f(x) = 3x+2

g(x) = x-3

f(x)-g(x) = 3x +2 - (x-3) = 3x + 2-x+3=2x+5

Answer 2

The answer is 2x + 5.

Explanation:

Given,

`f(x) = 3x + 2`,

`g(x) = x - 3`,

So,

`f(x) - g(x) = 3x + 2 - ( x - 3)` ( By substitution )

`= 3x + 2 - x + 3` ( By distribution property )

`=2x + 5` ( By operating like terms )

`\implies f(x) - g(x)=2x + 5`

Hence, last option is correct.
