Question

If f(x) = x + 4 and g(x) = x^2 - 4x + 3, then what is f(x) + g(x)?

a) x^2 - 4x + 7
b) x^2 - 3x + 7
c) x^3 + 3
d) x^2 - 5x + 7

Answer 1

To find f(x) + g(x), substitute the values of f(x) and g(x) into the expressions and combine like terms.

Step-by-step explanation:

To find f(x) + g(x), we first need to find the values of f(x) and g(x).

Given f(x) = x + 4 and g(x) = x^2 - 4x + 3, we substitute these values into the expressions.

So, f(x) + g(x) = (x + 4) + (x^2 - 4x + 3).

Combining like terms, we have f(x) + g(x) = x^2 - 3x + 7.

Therefore, the correct option is b) x^2 - 3x + 7.
