Question

How can we use transformations to graph this function? y=3x7^(-x)+2 Explain your steps.

Answer 1

y=0

Explanation:

so it has a steady slope

Answer 2

Sketch the graph of y=7x

Reflect the graph across the y-axis to show the function y=7^-x

Stretch the graph vertically by a factor of 3 to show the function y=3x7^-x

Shift the graph up 2 units to show the function y=3x7^-x +2
