Step-by-step explanation:
ranges are,
-1 , -11 and 7
hope this answer helps you dear!
Answer:
R = { - 11, - 1, 7 }
Substitute the values from the domain into f(x) for range
f(2) = - 2(2)² + 7 = - 2(4) + 7 = - 8 + 7 = - 1
f(- 3) = - 2(- 3)² + 7 = - 2(9) + 7 = - 18 + 7 = - 11
f(0) = - 2(0)² + 7 = - 2(0) + 7 = 0 + 7 = 7
Then
(2*(-8)^2)-(4*3)+(4*3^2)
128-12+36
152
Assuming you want an equation, y = -4/3x - 1
Formula is y = mx + b
m = slope= -4/3
b = y-intercept = -1
aggreed very mean.....
