Which best describes the end behavior of y =7x2? As x> 0 increases, f(x) decreases. As x < 0 decreases, f(x) decreases.
As x>0 increases, f(x) increases. As x < decreases, f(x) decreases.
As x > 0 increases, f(x) increases. As x < 0 decreases, f(x) increases.
As x > 0 increases, f(x) decreases. As x < 0 decreases, f(x) increases.

Kayla wants to find the width, ab, of a river. she walks along the edge of the river 65 ft and marks point c. then she walks 25 ft further and marks point d. she turns 90° and walks until her location, point a, and point c are collinear. she marks point e at this location, as shown. (a) can kayla conclude that δ and δ are similar? why or why not? (b) suppose de = 15 ft. what can kayla conclude about the width of the river?
