Question

Let f(x)=-3x and g(x) = 2x-1 Find the following: 4g(x) - f(x)

Answer 1

Answer:

11x-4

Step-by-step explanation:

f(x)=-3x

g(x) = 2x-1

4g(x) - f(x)

4(2x-1) - ( -3x)

Distribute

8x -4 +3x

Combine like terms

11x-4

Answer 2

Here, we are provided with two polynomials f(x) and g(x),and we need to find 4g(x) - f(x).

Given,

• f(x) = -3x
• g(x) = 2x - 1

Now,we need to find 4g(x) - f(x). We will simply substitute the given value of polynomials to get the answer.

$4g(x) - f(x)$

$4(2x - 1) - ( - 3x)$

Opening the parentheses,

$8x - 4 + 3x$

Now combing the like terms, and adding them,

$8x + 3x - 4$

$\boxed{11x - 4}$

This is our final result.
