Answer:
2x + 1.
Step-by-step explanation:
y=x^2 + x + 1
Using the algebraic derivative rule, if y = ax^n then y' = anx^(n-1) :
The derivative is 2x^(2 - 1) + 1x^(1-1)
= 2x^1 + x^0
= 2x + 1.
The average rate of change is m=5.

Answer: B and E are irrational numbers
Your best bet is A. 524
Use the formula V=4/3(pi)r^3 or

Not sure if that made sense but you need to multiply to radius(cubed) by pi and divide it by 4/3
Next time just google the volume formula of a sphere
