Question

What is the first step in writing f(x) = 6x2 + 5 – 42x in vertex form?

Factor 6 out of each term.
Factor 6 out of the first two terms.
Write the function in standard form.
Write the trinomial as a binomial squared.

Answer 1

the answer is c i just took the test

Answer 2

If we want to write the function in vertex form:
f ( x) = 6 x² + 5 - 42 x = 6 x² - 42 x + 5 = 6 ( x² - 7 x ) + 5 ...
First step is: C ) write the function in standard form ( y = ax² + b x + c )
