Find the output of the function y=−3x−7 when the input is −5 . (1 point)The correct output is .

Answer 1

To find the output of the function \( y = -3x - 7 \) when the input \( x \) is \( -5 \), we can substitute \( -5 \) for \( x \) in the equation:

\[ y = -3(-5) - 7 \]

Now, calculate \( -3(-5) \):

\[ -3(-5) = 15 \]

Now substitute this back into the equation:

\[ y = 15 - 7 \]

Now, calculate \( 15 - 7 \):

\[ y = 8 \]

Therefore, the correct output is \( 8 \).
