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:

walter needs to make at least 5 more cookies but no more than 40. 5 ≤ x ≤ 40

step-by-step explanation:

20 ≤ x + 15 ≤ 55

subtract 15 from all parts

20-15 ≤ x + 15-15 ≤ 55-15

5 ≤ x ≤ 40

this means how many more cookies he has to make

walter needs to make at least 5 more cookies, but no more than 40 cookies; 5 ≤ x ≤ 40
