If f(x) = x 2 + 1 and g(x) = 3x + 1, find [f(2)-g(1)] 2.
Question
If f(x) = x 2 + 1 and g(x) = 3x + 1, find [f(2)-g(1)] 2.
Solution
Sure, let's solve this step by step:
-
First, we need to find the values of f(2) and g(1).
-
For f(2), we substitute x = 2 into the equation f(x) = x^2 + 1. This gives us f(2) = 2^2 + 1 = 4 + 1 = 5.
-
For g(1), we substitute x = 1 into the equation g(x) = 3x + 1. This gives us g(1) = 3*1 + 1 = 3 + 1 = 4.
-
Now, we need to find the value of [f(2)-g(1)]^2. This means we subtract the value of g(1) from f(2) and then square the result.
-
So, [f(2)-g(1)]^2 = (5 - 4)^2 = 1^2 = 1.
So, [f(2)-g(1)]^2 = 1.
