Answer:

Positive:  (-1,3)

Negative: (-\infty,1)\cup (3,\infty)

Step-by-step explanation:

The graph represents a parabola that has a maximum vertex at (1,4).

The portion of the graph above the x-axis is considered positive

For -1\:, the function is positive.

We can write this in interval notation as: (-1,3)

For x\:>\:3 or x\: , the function is negative.

We can write this in interval notation as: (-\infty,-1)\cup (3,\infty)

Which statement is true?
krok68 [10]

Answer:

(B) 1.2 > -6.9

Explanation:

The negative numbers/decimals are always to the left of the 0 on a number line. They are not positive.

The positive numbers are always to the right of the 0 on a number line. They are always greater than negative numbers.

6.9 might be greater than 1.2 if it is a positive number, but if it is a negative number, 1.2 is greater.
