f(x) = 6x² + 5 - 42x

first step in writing the f(x) in vertex form? WRITE THE FUNCTION IN STANDARD FORM.

f(x) = 6x² - 42x + 5

Exponents must be in decreasing order. 

Answer:

Option 3rd is correct

Write the function in standard form.

Step-by-step explanation:

The standard form of the quadratic equation is given by:

[tex]y=Ax^2+Bx+C [/tex]

As per the statement:

Given the function:

[tex]f(x) = 6x^2+5-42x[/tex]

We have to find the first step writing f(x) vertex form.

Firstly, write the given function in standard form

by definition we have;

[tex]f(x) = 6x^2-42x+5[/tex]

Therefore, the first step writing f(x) vertex form is, Write the function in standard form.
