Given the function f(x)=x2+2x+1, find:
f(2b)
All you have to do is substitute x for 2b in the original equation.
I tried that
To find f(2b) for the given function f(x) = x^2 + 2x + 1, we need to substitute 2b in place of 'x'.
Step 1: Replace 'x' with '2b' in the function f(x).
f(2b) = (2b)^2 + 2(2b) + 1
Step 2: Simplify the expression.
f(2b) = 4b^2 + 4b + 1
Therefore, the value of f(2b) for the given function is 4b^2 + 4b + 1.
