Answer 4

Do you know the formula to calculate it? :D

Answer 5

The formula is A = f(b) - f(a) / b - a

Answer 9

yeah, it means we need the values of x=a and x=b ?

Answer 10

i have a graph u want to see it this is the question I have to go have dinner please answer this ill be right back

Answer 11

f(x)=9x^2-25 this is the function of the graph

Answer 12

So what's the interval?

Answer 13

i think we can take it from the x-intercepts, right ?
9x^2 - 25 = 0
solve for x's first

Answer 14
