Question

If f(x)=x^2+2x+3, find f(1)

Answer 1

To solve this problem, we must substitute in 1 for the variable x in the equation. This is because the function as written is f(x), meaning that the function is evaluated as x currently, but we want to evaluate it at 1. To do this, all we have to do is replace each variable x with a 1 and simplify.

f(x) = x^2 + 2x + 3

f(1) = (1)^2 + 2(1) + 3

To simplify, we first to compute the exponents. This is because of the order of operations, which says that we should solve parentheses first, exponents next, then multiplication/division, then addition/subtraction last.

f(1) = 1 + 2(1) + 3

Next, as outlined above, we should perform the multiplication.

f(1) = 1 + 2 + 3

Finally, we can finish solving by adding together the remaining terms.

f(1) = 6

Therefore, your answer is 6.

Hope this helps!
