Find the output of the function ◂=▸𝑦=−3𝑥−7 when the input is −5

Answer 1

To find the output of the function, we need to substitute the input value into the function and solve for the output.

Given that the input is -5, we can substitute this value for 'x' in the function y = -3x - 7:

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

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