Question

I honsetly don't even know.

Answer 1

[-5,-3]

Let's verify

f(-5)

• 2(-5)²-5
• 2(25)-5
• 45

f(-3)

• 2(-3)²-5
• 2(9)-5
• 18-5
• 13

Rate of change

• f(-5)-f(-3)/-5-3
• 45-13/-8
• -4

Answer 2

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)
