The graph shows the amount of a chemical in a patient's body at different times measured in hours since the levels were first checked. Could the amount of this chemical in the patient be decaying exponentially? Explain how you know.

For f(x)=2x+1 and g(x)= x^2 -7, find (f•g)(x)

Sienna planned a trapezoid-shaped garden, as shown in the drawing below. she decides to change the length of the top of the trapezoid-shaped garden from 32 ft to 24 ft. which expression finds the change in the scale factor?

The boiling point of water at an elevation of 0 feet is 212 degrees fahrenheit (°f). for every 1,000 feet of increase in elevation, the boiling point of water decreases by about 2°f. which of the following represents this relationship if b is the boiling point of water at an elevation of e thousand feet? a) e = 2b - 212 b) b = 2e - 212 c) e = -2b + 212 d) b = -2e + 212
