F f(x) = 4 – x2 and g(x) = 6x, which expression is equivalent to (g – f)(3)?
Oliga [24]
<h2>Subtracting Functions</h2><h3>Answer:</h3>

6(3) -4 +3^2

<h3>Step-by-step explanation:</h3>

Given:

f(x) = 4 -x^2

g(x) = 6x

Before we find the expression of (g -f)(3), we must first know how (g -f)(x) is defined.

(g -f)(x) = g(x) -f(x) \\ (g -f)(x) = 6x -(4 -x^2) \\ (g -f)(x) = 6x +x^2 -4 \\ (g -f)(x) = x^2 +6x -4

Now we can find (g -f)(x).

(g -f)(3) = (3)^2 +6(3) -4

vlada-n [284]
One foot is 12 inches, multiply that by 3 and you have 1 yard.  
To get one yard to 3 yards ad 36+36+36 or 36 X 3 

3 yards is 108.

Drugs jump was 3 yards. 

3 yards = 108
3 yards = Doug's jump
Doug's jump = 108

108- 98 = 10

Doug's jump was 10 inches longer

First you would have to multiply 12 times 5 (60) then multiply 7 times 18 (126) you subtract both [ 126 - 60] = (66) that would be your final answer. They both need to have worked 66 minutes to have the same number of boxes.
