PLEASE HELP WITH THIS CALCULUS PROBLEM!?

Question

y=x^2-9 
y=7 
find the area enclosed by the curve.

Answer 1

The curve equation y  = x ² - 9

And the line equation y  = 7

Equate the y  forms.

x ² - 9 = 7

x ² =  9 + 7

x ² = 16

x ² = ± 4

So the limits are -4 and 4.

Formula for the area between curve and line

In this case f (x ) = 7 and g (x ) = x ² - 9.

a  = -4, b  = 4.
