f(x)=2x+5, find f(3)
would this be worked out liek this
2(3)+5=11
Your answer is correct but
improve your mathematical form and write is this way:
f(x)= 2x+5
f(3)= 2(3)+5
= 11
Yes, that is correct! To evaluate the function f(x) at a specific value, you substitute the given value into the function and simplify. In this case, the function f(x) is given as f(x) = 2x + 5 and we want to find f(3). By substituting x = 3 into the function, we get f(3) = 2(3) + 5. Simplifying further, we have f(3) = 6 + 5 = 11. Therefore, the value of f(3) is 11.
