What is the equation ? Is there a picture to the question.
Answer:
The option that no represent a linear function is 
Step-by-step explanation:
we know that
The graph of a linear function is a straight line
The equation of a linear function in slope intercept form is equal to

where
m is the slope
b is the y-intercept
<u><em>Verify each case</em></u>
option 1) we have

This option represent a linear function
where
m=3
b=-2
option 2) we have

This option represent a linear function
where
m=1
b=0
This option represent a linear direct variation function
option 3) we have

This option not represent a linear function
This option represent a exponential function
option 4) we have

This option represent a linear function
where
m=3
b=0
This option represent a linear direct variation function
Answer:
f(0)= 3-2^0 --> 3-1 =2
f(-1)= 3 - 2^-1 --> 3 - 1/2 -->5/2 = 2,5
Step-by-step explanation: F(0) means if x=0 so the first you just take x and replace it with 0 and the second you replace x by -1.
Something that is elevated by 0 is always going to be 1
Hope this make sense :)
90% of 130 is 117 because 10% is 13 and 13x9 is 117 so that is part a. 130-117 is 13 so that is part b. And part c is correct because 100%-90%=10%. I hope this is helpful.
Answer:
negative
Step-by-step explanation:
the reason why is it is -2 and that makes it negative
