For which intervals is the function positive?
select each correct answer.

Alright, lets get started.

When teh function is above the x axis, it is said to be positive.

When the function is below the x axis, it is said to be negative.

Now, looking at the graph provided with question, from -8 to -6, the function is above the x axis.

After -6, function goes below the x axis till -2.

In between -2 to 4, function again goes above x axis.

Means two times function goes above the x axis.

Between -8 to -6

Between -2 to 4

Hence there are two intervals where function is positive.

Hope it will help :)

12.4, 12.387, 12.26, 12.252, 6.241, 6.2, 6.015, 6.009, 1.411, 1.2, 1.056, 1.007, 0.31,   0.13, 0.5, 0.04

the polynomial is a perfect square trinomial of the form a^2-2ab+b^2:

option a. true

step-by-step explanation:

9x^2-12x+4

comparing with the form a^2-2ab+b^2

1.) a^2=9x^2

solving for a: square root both sides of the equation:

sqrt(a^2)=sqrt(9x^2)

a=sqrt(9) sqrt(x^2)

a=3x

2.) b^2=4

solving for b: square root both sides of the equation:

sqrt(b^2)=sqrt(4)

b=2

to be a perfet square trinomial 2ab must be equal to 12x. let's check:

2ab = 2 (3x) (2)

2ab = 12x

correct
