I honsetly don't even know.

Step-by-step explanation:

the correct answer is B. [-5, -3]

for x = -5 => f(-5) = 2(-5)²-5

= 50-5

= 45

for x = -3 => f(-3) = 2(-3)² -5

= 18-5

= 13

the change = 45-13 = 32

(this is the greatest)

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

20%
