If the function is -x^2 -4x + 2 (you skipped the operator between -4x and 2), then:

1) The domain is all the real numbers (-infinity, + infinity)

2) The range is all the real numbers below 6, given that the vertex is (2,6) and the function opens down (because the coefficient of x^2 is negative).

3) The function increases over the interval (-infinity, 2) and decreases over the interval (2,+infinity).

4) The y-intercept is the value of the function when x =0, so it is 2 (positive).

Then, the only true statement is that the range is y such that y is 6 or below

A. 8^9/2= around 11585.2375; (sqrt8)^9= around 11585.2375. So choice A shows a pair of equivalent expressions.

B. (3sqrt125)^9=1,953,125; 125^9/3=1,953,125. So choice B also shows a pair of equivalent expressions.

C. 12^2/7= around 2.03394; (sqrt12)^7= around 5,985.96759. So choice C does not show a pair of equivalent expressions.

D. 4^1/5=around 1.31951; (sqrt4)^5=32. So choice D also doesn't show a pair of equivalent expressions.

Your answers are A and B.

I hope this helps ;)

Help I’m stuck on this question:
LUCKY_DIMON [66]

Answer:

C

Step-by-step explanation:

Let d = the distance from camp

d < 1.8 + 2.6 = 6.4    

d > 2.8

so 2.8 < d < 6.4,  therefore d could be 5.3
