Range goes from the lowest point on a graph to the highest point, not including anything in between those 2 extremes. We will evaluate the quadratic for the values given. First f(2):

$f(2)=(2)^2-5$ so

f(2) = -1

Now, f(4):

$f(4)=(4)^2-5$ so

f(4) = 11

Now, f(7):

$f(7)=(7)^2-5$ so

f(7) = 44

The lowest y value is -1 and the highest is 44, so the range is from -1 to 44 (I can't tell which of your choices reflects that because it's too small!)

In the figure, parallel lines r and s are cut by line t

Lady_Fox [76]

Answer:

x = 49

Step-by-step explanation:

Since the line is parallel, the value of 2x - 8 is equal to 90.

=> 2x - 8 = 90

=> 2x = 98

=> x = 49
