Describe how you can graph an exponential function with the help of doubling time or half-life. What is the general shape of an exponential growth function? What is the shape of an exponential decay function? Question content area bottom Part 1 Describe how you can graph an exponential function with the help of doubling time or half-life. Choose the correct answer below. A. Start at the point left parenthesis 0 comma Upper Q 0 right parenthesis, where Upper Q 0 is the initial value of the function. For an exponentially growing quantity, the value Q of the function is 2Upper Q 0 after one doubling time, 4Upper Q 0 after two doubling times, 8Upper Q 0 after three doubling times, and so on. Fit a curve between these points. B. Start at the point left parenthesis 0 comma Upper Q 0 right parenthesis, where Upper Q 0 is the initial value of the function. For an exponentially growing quantity, the value Q of the function is .5Upper Q 0 after one doubling time, .25Upper Q 0 after two doubling times, .125Upper Q 0 after three doubling times, and so on. Fit a curve between these points. C. Start at the point left parenthesis 0 comma Upper Q 0 right parenthesis, where Upper Q 0 is the initial value of the function. For an exponentially growing quantity, the value Q of the function is 2Upper Q 0 after one doubling time, 4Upper Q 0 after two doubling times, 6Upper Q 0 after three doubling times, and so on. Fit a curve between these points
