Question

Which of the following represents this function written in standard form?

Answer 1

The answer is D because simplifying it equals the equation given.

Answer 2

Answer:

Option D - $y=2x^2-10x-12$

Step-by-step explanation:

Given : Function $y=2(x+1)(x-6)$

To find : Which of the following represents this function written in standard form?

Solution :

Step 1 - Write the function

$y=2(x+1)(x-6)$

Step 2 - Solve by multiplying the brackets

$y=2(x^2-6x+x-6)$

$y=2(x^2-5x-6)$

Step 3 - Multiply bracket by 2 and solve

$y=2x^2-10x-12$

Therefore, The standard form of the function is $y=2x^2-10x-12$

So, Option D is correct.
