F(x) = -0.5x2, if f(x) = -112.5, what is the value of 'x'?<br> ?
sleet_krkn [62]

Answer:

x = ± 15

Step-by-step explanation:

Given f(x) = - 0.5x² and f(x) = - 112.5 , then equate right sides

- 0.5x² = - 112.5 ( divide both sides by - 0.5 )

x² = 225 ( take square root of both sides )

x = ± \sqrt{225} = ± 15
