If 7 is an element in the domain of ​f(x) =5x-17 / 5

​, what is the corresponding element in the​ range?
the corresponding element is

1 answer

To find the corresponding element in the range for the function \( f(x) = \frac{5x - 17}{5} \) when \( x = 7 \), we can substitute \( 7 \) into the function.

  1. Substitute \( x = 7 \) into the function:

\[ f(7) = \frac{5(7) - 17}{5} \]

  1. Calculate \( 5(7) - 17 \):

\[ 5(7) = 35 \] \[ 35 - 17 = 18 \]

  1. Now substitute back into the function:

\[ f(7) = \frac{18}{5} \]

Thus, the corresponding element in the range is:

\[ \frac{18}{5} \]

So the answer is:

\[ \frac{18}{5} \text{ or } 3.6 \]
