Answer: C. Write the function in standard form.Explanation:The standard form of the quadratic equation is given by:y=ax^2+bx+c.Given the function:f(x) = 6x^2+5-42x;We have to find the first step writing f(x) vertex form.Firstly, write the given function in standard form by definition we have;f(x) = 6x^2-42x+5.Therefore, the first step writing f(x) vertex form is, Write the function in standard form....
