If f(x) = -x^2 + 6x - 1 and g(x) = 3x^2 - 4x-1, find (f - g)(x). A. (f- g)(x) = -4x^2 - 2x
B. (f- g)(x) = 2x^2 + 2x-2
C. (f- g)(x) = 4x^2 - 10x
D. (f - g)(x) = -4x^2 + 10x

D

Step-by-step explanation:

(f-g)(x)= -x^2+6x-1- (3x^2-4x-1)

(f-g)(x)= -x^2+6x-1 -3x^2+4x+1

(f-g)(x)= -x^2-3x^2+6x+4x-1+1

(f-g)(x)= -4x^2+10x

let x be the money she spent so that she can earn the free t-shirt.

since, she already spent $112.49

⇒

also, as per the statement: jennifer must spend $250 or more in order to qualify for a free t-shirt at the store.

then,

we have an inequality i.,e

subtract 112.49 from both sides we get;

therefore, $137. 51 more money does jennifer need to spend so that she can earn the free t-shirt

i think the correct option is the second option.
