Use the quadratic function to predict f(x) if x equals 2.

f(x) = −3x2 + 180x − 285

a) f(2) = 125

b) f(2) = 87

c) f(2) = 63

d) f(2) = 111

c

Step-by-step explanation:

To evaluate substitute x = 2 into the quadratic

f(2) = - 3(2)² + 180(2) - 285 = - 12 + 360 - 285 = 63 → c

she was supposed to add the hours(38.5) and multiply the amount of money she earned(7.50) resulting in $288.75 .

correct me if i'm wrong and if it is i'm truly sorry.
