With?

OpenStudy (freemap):

What is the equation of the function shown in the graph, given that the equation of the parent function is f(x) = 3.5x?

OpenStudy (freemap):

A. g(x) = 3.5x + 1.5 B. g(x) = 3.5x + 1 C. g(x) = 3.5x – 1 D. g(x) = 3.5x – 2

OpenStudy (anonymous):

Which way did it move from the parent function?

OpenStudy (michele_laino):

Hint: as we can see the asymptote has this equation: \(y=-2\), so, please use the result of the previous exercise

|dw:1445883748169:dw|

OpenStudy (michele_laino):

what is the right option?

OpenStudy (freemap):

d?

OpenStudy (michele_laino):

hint: I choose function in A. I can write this: \[g\left( 0 \right) = {3.5^0} + 1.5 = 1 + 1.5 = 2.5\] so the point \(0,2.5\) blongs to the graph of the function in A. Is it true for your graph?

OpenStudy (freemap):

no

OpenStudy (michele_laino):

correct! since your graph passes at point \((0,-1)\)

OpenStudy (michele_laino):

Now, I choose the graph of option D. So, I can write: \[g\left( 0 \right) = {3.5^0} - 2 = 1 - 2 = - 1\] so the point \((0,-1)\) belongs to the graph of function in C. SO, what can you conclude?

OpenStudy (michele_laino):

oops..So*

OpenStudy (michele_laino):

sorry ...belongs to the graph of the function in D* not in C
