Find f(-10).
marysya [2.9K]

Answer: -75

Explanation: In this problem, we're given the function f(x) = 7x - 5 and we're asked to find f(-10).

To find f(-10) or the value of the function when <em>x = -10</em> we simply substitute -10 in for <em>x</em> in our function.

So we have 7(-10) - 5 or -70 - 5 which equals -75.

So f(-10) or the value of the function when <em>x</em> <em>= 10</em> is -75.

Since your answer to this problem was <em>a</em>, your answer is correct.
