identify the quadratic function(s). (select all that apply).

a.) y(y + 4) - y = 6

b.) (3x + 2) + (6x - 1) = 0

c.) 4b(b) = 0

d.) 3a - 7 = 2(7a - 3)

The quadratic function are:

 option: A   A)  y(y + 4) - y = 6

 Option: C   C.)  4b(b) = 0

We know that the general equation of a quadratic equation in terms of a variable x is given by:

A)

y(y + 4) - y = 6

On simplifying the terms we have:

Hence, option: A is correct.

B)

(3x + 2) + (6x - 1) = 0

Hence, it is a linear equation.

Hence, option: B is incorrect.

C)

4b(b) = 0

it could also be written as:

Hence, it is a quadratic equation.

Hence, option: C is correct.

D)

3a - 7 = 2(7a - 3)

which is again a linear equation.

Hence, option: D is incorrect.

the slope of the first function is -3. (3/1)

the slope of the second function is 1. (13-10/6-3).

since |-3| is greater than |1|, the function with the steepest slope is the first.

y > 1/3x

y < = -x + 4
