Pls show work, ASAP PLSThanks in advance

The parent function is F(x)= x.  Whenever it is shifted up or down, you just add (or subtract) that at the end.  So it would be f(x)= x - 1.  Then it says stretched vertically.  If it is stretched vertically, you multiply x by that number.  If it is stretch horizontally, you mulitply by the fraction of 1/ that number.  In this case it is stretched vertically, so we will use two.  Your final answer would be f(x)= 2x - 1

Step-by-step explanation:

c is the correct answer

step-by-step explanation:

94

step-by-step explanation:

average the numbers and use a variable to figure out the minimum to get a 90.

(79+94+91+92+x)/5=90

x = 94
