The graphs below represent the equations y = 2* and y = 2x + 1.
graph 1
graph 2

a. Graph 1 is y=2^x and Graph 2 is y=2x+1

b. The slope increases over time on Graph 1, and remains the same on Graph 2

c. Graph 1 is exponential (y=2^x) and Graph 2 is linear (y=mx+b)

Hope this helps!

Step-by-step explanation:

a:  y=2* is exponential, so it is graph 1 (it makes a curve) y=2x+1 is linear (makes a line), and it has a slope of 2 and a y-intercept of 1, so y=2x+1 is graph 2!

b. slopes of Exponential Functions usually continue to increase (unless the number that is being affected by the exponent x is less than 1, in which they would continue to decrease), and linear functions have a set slope (m in y=mx+b)

c. Explanation is in the answer (it says to explain)

example answer: "to determine if a sum is reasonable you can round each number to the nearest whole and compare the estimated sum to the actual sum."

hope this you and anyone else who needs the answer : ^)
