You know 36 is 90% of a value, so it will equal 90/100.
Multiply 90/100 types x (value). Easiest way is to simplify 90/100 = 9/10.
x = 36 / 9/10
x = 360 / 9
x = 40
Therefore, the value would be 40.
(n -12)(n +3)= 0
n = 12, n = -3
Divide both sides by f then cancel out
Answer:
EX: f(x) ≥ 0 over the interval [-1, 1].
