Answer:
46 and 277
Step-by-step explanation:
Given
f(x) = - 8x - 11 ← substitute x = 3, x = - 4 into f(x)
f(3) = - 8(3) - 11 = 81 - 24 - 11 = 81 - 35 = 46
f(- 4) = - 8(- 4) - 11 = 256 + 32 - 11 = 288 - 11 = 277

Plug the numbers 4 and 7 into the formula.
Now evaluate them to get
16+49=65
To get c, take the square root of 65
You need to simplify it first.
