Question

Given the function rule f(x)=5(10-x)+2, find the value of f(3).

Explain in words what you need to do in order to find a function value such as f(3).

Find the value. Be sure to show your work.

I have no clue what the answer is and I suck at math.

I tried to do it on brainly but it said "Don't use such phrases here, not cool! It hurts our feelings :(" when I try to post the question.
It's not that hard.
substitute 3 for x
f(3)=5(10-3)+2,
= 5(7) + 2
= 35 +2
= 37
Thank you anon
