For f(x)=3x+1 and g(x)=x^2-6, find (f•g)(x).
1 answer:
Answer & Step-by-step explanation:
When we see (f * g)(x), it means that we are going to be multiplying f(x) and g(x) together.
<em>f(x) = 3x + 1</em>
<em>g(x) = x² - 6</em>
(3x + 1)(x² - 6)
Multiply each term from the first parentheses to the second parentheses.
3x³ - 18x + x² - 6
Combine like terms and make sure the expression is in standard form.
3x³ + x² - 18x - 6
So, your answer will be letter choice B.
