Determine which of the following graphs does not represent a function.

(Help me ASAP)

D

Step-by-step explanation:

one way to determine whether or not something is a function is to use the vertical line test

You can draw vertical lines all along the figure and if the same vertical line touches 2 parts of the graph we know this is not a function due to there being 2 outputs for the same x value

d is a vertical line and therefore will not pass this test

26 is 33.33% of 78

step-by-step explanation:

26 is what percent of 78?

26 is p% of 78

equation: y = p% * x

solving our equation for p

p% = y/x

p% = 26/78

p = 0.3333

convert decimal to percent:

p% = 0.3333 * 100 = 33.33%

what is the model?
