Question

In a exponential function can the y value be adding instead of multiplying? I am doing a problem with a exponential function and the y value is adding by 4 each time and I think that it can but I just want to make sure

Answer 1

can you be more specific?

Answer 2

This is the table I was wondering if it could be a exponential function if the Y value is adding I know it can be if its multiply or dividing but not sure about when it is adding I think it can be but not sure

Answer 3

Answer 4

no this is not an exponential function

Answer 5

Can you please explain to me why its not I would like to know how to solve them my self :)

Answer 6

for each increase of 1 in \(x\), \(y\) increases by 4
that means it is a linear function with slope \(4\)

Answer 7

think of the graph: over one, up 4, over1, up 4, over 1, up 4
rate of change is a constant, the graph is a line, the slope is 4

Answer 8

in fact, it is \(y=4x\) since you multiply the first number by 4 to get the second number

Answer 9

Oh so it is a exponential function?

Answer 10

Answer 11

no
it is a linear function

Answer 12

exponential function looks like
\[f(x)=b^x\]

Answer 13

Oh ok
