F(x)=x²+3x ; [-2;3]⇒Δf/Δx=(f(3)-f(-2))/(3-(-2))=4 (A)
f(x)=3x-8 ; [4;5]⇒Δf/Δx=<span>(f(5)-f(4))/(5-4)=3 (B)
f(x)=x</span>²-2x ;[-3; 4]⇒<span>Δf/Δx=(f(4)-f(-3))/(4-(-3))= -1 (C)
f(x)=x</span>²-5 ;[-1; 1]⇒<span>Δf/Δx=(f(1)-f(-1))/(1-(-1))= 0 (D)

Answer: A and C
Step-by-step explanation:
So the largest rectangle has sides of 5 length and 2+4 width or 6 right. so 5*6=30 Now we have to find which of these expressions solve to get 30. I would just solve them all but the answer is
A and C
What is equivalent to 9?
9/1 = 9
9/1 is equivalent to 9.
Answer:
Four (4) pounds
Step-by-step explanation:
Because we required two (2) pounds to stretch the spring eight (8) inches, we need double the force to stretch it sixteen (16) inches. Sixteen is just double the original amount, meaning we need four (4) pounds to stretch the spring sixteen inches.
Hope this helps!
