I need help brainliest!!!

Step-by-step explanation:

First one: function and linear

Second one: function and non-linear

Third one: not a function and linear

Step-by-step explanation:

• The first one is set in the linear function formula y=mx+b, so it is a linear function.

• The second one is a non-linear because functions with exponents have different shapes and can intersect more than once unline linear functions.

• The third one isn't a function but it is linear because it isn't set equal to a variable and it would become a linear if you simply it to isolate a variable.

I hope this helps!!!

answer is 67%

step-by-step explanation:

easy its decreasing

step-by-step explanation:

because its top point is at the to of the graph on the left side (atleast from the veiw i see it) now if that top point wast in the lower part of the graph it would be increasing hope this have a nice day
