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)

The answer will be 4/8 but the simplest form is 1/2
19+19+4.4+17.2=59.6 is the perimeter
Answer:
2
Step-by-step explanation:
5-3=2
Formula: SA = (2 × π(pie) × radius × height) + (2 × π(pie) × radius square.)
So the equation will be SA=( 2 × 3.14 × 2 × 4) + ( 2 × 3.14 × 2²)
Then, we will get ↓ ↓
SA= 50.24 + 25.12
<u>SA = 75.36 in</u><u>²</u>
