A quick question about transformations of graphs, anyone up for it??

Question

i have two graphs:

graph one has an equation of y = 64.565e-0.0598x

Therefore the y-intercept is 64.565

Graph two has the equation of y = 70.91e-0.0695x

Therefore the y-intercept is 70.91

I need to transform one of the equations so that both of the equations have the same y-intercept.

PLEASE HELP IN ANY WAY IF YOU CAN!

thankks veryy veryy much :)

Answer 1

Modify second graph

y = 70.91e-0.0695x

by subtracting the difference of 70.91and 64.565 i.e 70.91- 64.565 = 6.345

second equation becomes

y = 70.91e-0.0695x - 6.345

Both these equations will have the same intercept on y - axis

Answer 2

Hi,

You are given these 2 equations:

y = 64.565e^(-.0598x)

y = 70.91e^(-.0695x)

By changing them into

y = 64.565e^(-.0598x)

y = 70.91e^(-.0695(x+1.348762576)), they have a common y intercept of 64.565.

By changing them into

y = 64.565e^(-.0598(x-1.56754179))

y = 70.91e^(-.0695(x), they have a common y intercept of 70.91.

I hope that helps!! :-)
