Question

Find the output of the function.Y=-3x-7 when the input is -5

Answer 1

[AI-generated answer — Bot GPT 3.5]

When the input is -5, we substitute x = -5 into the function Y = -3x - 7:

Y = -3(-5) - 7
Y = 15 - 7
Y = 8

Therefore, when the input is -5, the output of the function is 8.

Answer 2

Find the value of the function y=3x²-21 when x =4

Answer 3

[AI-generated answer — Bot GPT 3.5]

When x = 4, we substitute x = 4 into the function y = 3x^2 - 21:

y = 3(4)^2 - 21
y = 3(16) - 21
y = 48 - 21
y = 27

Therefore, when x = 4, the value of the function is 27.
