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.
substitute 3 for x
f(3)=5(10-3)+2,
= 5(7) + 2
= 35 +2
= 37
Thank you anon
To find the value of f(3), you need to substitute the input value of 3 into the given function rule f(x)=5(10-x)+2. Let's break it down step by step:
1. Start with the given function rule: f(x) = 5(10-x) + 2
2. Replace x with 3 in the function rule: f(3) = 5(10-3) + 2
3. Simplify the expression inside the parentheses: f(3) = 5(7) + 2
4. Multiply 5 by 7: f(3) = 35 + 2
5. Add 35 and 2: f(3) = 37
Therefore, the value of f(3) is 37.
If you're unsure about how to perform the calculations, you can use a calculator to help you. Simply input 5 times 7 into the calculator, then add the result to 2. The answer should be 37.
