 Question 595605: if f(x)= x^2+3, find f(5) could you also show how you figured it out?Answer by bucky(2189)   (Show Source): You can put this solution on YOUR website!Given that f(x)= x^2+3 . when you are asked to find f(5) that means that you are to find the value of the function when x equals 5. . So start with f(x)= x^2+3 and substitute 5 wherever you find an x to get: . f(5)= 5^2+3 . square the 5 on the right side to get: . f(5) = 25 +3 . and do the addition on the right side to get the answer: . f(5) = 28 . Hope this helps you to understand what you are to do when you are asked to find f(x) in any similar problem. Just substitute the value of x that you are given into the right side of the equation and do the mathematics on the right side to get the answer. .
