<span>f(x) =-(x+9)(x-21)
Manipulating algebrically,
We get,
</span>f(x) =-(x+9)(x-21)
= -(x^2 -21x + 9x - 189)
= -(x^2 -12x - 189)
= -x^2 + 12x + 189
Axis of symmetry = -b/2a
plugging the values,
x = -12/-2
= 6
Answer:
{ - 9, - 7, - 3, - 1 }
Step-by-step explanation:
To obtain the range substitute the values of x from the domain into f(x)
f(- 2) = - 2(- 2) - 5 = 4 - 5 = - 1
f(- 1) = - 2(- 1) - 5 = 2 - 5 = - 3
f(1) = - 2(1) - 5 = - 2 - 5 = - 7
f(2) = - 2(2) - 5 = - 4 - 5 = - 9
range is { - 9, - 7, - 3, - 1 }
Answer:
Jerry paid $500.50.
Step-by-step explanation:
