Find all real values of $v$ that satisfy the equation $(v+6)^2 = 324$. if you find more than one, then list your values in increasing order, separated by commas.

Estimate the area under the curve f(x) = 16 - x^2 from x = 0 to x = 3 by using three inscribed (under the curve) rectangles. answer to the nearest integer.

If f(x) = 4x - 3 and g(x) = x + 4, find (f - g) (x)
