Explain why each graph is or isnt a function

B and C are functions but A and D are not

Step-by-step explanation:

Vertical line testing. You draw a vertical line. If the vertical lines passes through one line, its a function. It it passes through more than one line, its not. Or in other words, each input (x-value) has its own output (y-value)

only c is a function.

a, b, and d all fail the vertical line test, meaning their x values can have multiple outputs.

75

step-by-step explanation:

you do x-29=46 (the number of cantaloupes sold)

in order to find x, you have to find what minus 29 equals 46, meaning you'd have to add 29 to 46.

29+46=75

if you replace x with 75, the equation looks like:

75-29=46

x=75

good luck on your studies! : )
