Question

7. Consider the functions below.
f(x) = 2x + 3x - 5
9(x) = 5x + 4x - 1
which of the following is the resulting polynomia
f(x) is subtracted from g(x)
a
-3r-*- 4
-3° +7x - 6
3r+*+ 4
3x² + 78-6

Answer 1

Answer:

$3{x}^{2} + x + 4$

Step-by-step explanation:

Assuming the polynomials are

$f(x) = 2 {x}^{2} + 3x - 5$

and

$g(x) = 5 {x}^{2} + 4x - 1$

When f(x) is subtracted from g(x), we get;

$g(x) - f(x) = 5 {x}^{2} - 2 {x}^{2} + 4x - 3x - 1 - - 5$

We perform the subtracttion to get:

$g(x) - f(x) = 3{x}^{2} + x + 4$

Therefore the correct answer is

$3{x}^{2} + x + 4$
