Hi, i need help in this

- 53, - 207, - 7

Step-by-step explanation:

To obtain f(- 2), substitute x = - 2 into f(x), that is

f(- 2) = - 9(- 2)² + 5(- 2) - 7 = - 9(4) - 10 - 7 = - 36 - 10 - 7 = - 53

(b)

Similarly substitute x = 5 into f(x)

f(5) = - 9(5)² + 5(5) - 7 = - 9(25) + 25 - 7 = - 225 + 25 - 7 = - 207

(c)

f(0) = - 9(0)² + 5(0) - 7 = 0 + 0 - 7 = - 7

i believe

step-by-step explanation:

from my conclusion c

step-by-step explanation:

y = | -2(-2) |     →     y = | 4 |     →     y = 4       ⇒   (-2, 4)

y = | -2(-1) |     →     y = | 2 |     →       y =   2       ⇒   (-1, 2)    

y = | -2(0) |     →     y = | 0 |     →       y = 0         ⇒   (0, 0)

y = | -2(1) |   c →     y = | -2 |     →     y =   2         ⇒   (1, 2)    

y = | -2(2) |     →     y = | - 4 |     →     y =   4         ⇒   (2, 4)
