Question

Given the function below, find /(-7) (X) = -2x-1

Answer 1

For this case we have a function of the form$y = f (x)$where:

$f (x) = - 2x-1$

We must find the value of the function when$x = -7$. So:

$f (-7) = - 2 (-7) -1$

By definition we have to:

$- * - = +\\f (-7) = 14-1 = 13$

Thus, the value of the function is $y = 13$

Answer:

$y = f (-7) = 13$
