Question

The domain for f(x) and g(x) is the set of all real numbers.

Let f(x) = 3x + 5 and g(x) = x2.

Find g(x) − f(x).

x2 − 3x − 5

x3 − 5

3×2 − 5

3×3 − 5×2

    Hey there,

    Your question states: 

    The domain for f(x) and g(x) is the set of all real numbers.

    Let f(x) = 3x + 5 and g(x) = x2.

    Find g(x) − f(x).

    So, if \boxed{\boxed{f(x) = 3x + 5 \ and \ g(x) = x2.}}, and what we are trying to figure out is g(x) - f(x), would would have ti find an expression that would by means fit with f(x) = 3x + 5 and g(x) = x2.

    I would say that the answer would be x2 − 3x − 5.

    By plugging in the f(x) = 3x + 5 and g(x) = x2, I believe that this would make more sense.

    Hope this helps.

    g(x) − f(x) = x^2 – ( 3x + 5)
    g(x) − f(x) = x^2 – 3x – 5

    answer is A. first one
    x^2 – 3x – 5
