40 Select the Window Setting [ - 10,50]x [0.60]. A population has a limiting value of 40 and a logistic rate of 0. 15 Use the a and k-sliders to graph the function f(t) = The 1 + be- 0.15t initial population at time t= 0 is 5. Use the b-slider to find the value of b that gives f(0) = 5 Use the interactive figure to find your answer. Use the left and right arrow keys to move along a slider as needed.
