If f(x) = x 2 + 1 and g(x) = 3x + 1, find f(2) + g(3).
Question
If f(x) = x 2 + 1 and g(x) = 3x + 1, find f(2) + g(3).
Solution
Sure, let's solve this step by step:
-
First, we need to find the value of f(2). To do this, we substitute x = 2 into the function f(x) = x^2 + 1. This gives us f(2) = 2^2 + 1 = 4 + 1 = 5.
-
Next, we need to find the value of g(3). We substitute x = 3 into the function g(x) = 3x + 1. This gives us g(3) = 3*3 + 1 = 9 + 1 = 10.
-
Finally, we add the results of f(2) and g(3) together. This gives us 5 + 10 = 15.
So, f(2) + g(3) = 15.
