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

y=0

Step-by-step explanation:

so it has a steady slope

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                        

Step-by-step explanation:

answer: b.

step-by-step explanation:

the y coordinate for point b is 0, and answer b is the only one with that y coordinate.

9 sandwiches per hour

step-by-step explanation:

when we have a rate, we want a 1 in the denominator

27/3 = 9

27 sandwiches/ 3 hours = 9 sandwiches/hour
