Answer:
See the attached figure
y-intercept is the value of y when x = 0
Given the functions:
y = 3^x ⇒ the graph with the blue color
y = 2(1/2)^x ⇒ the graph with the red color
y = (1/4)^x ⇒ the graph with the green color
<u>As shown:</u>
<u>y = 3^x</u>
y-intercept at (0, 1)
graph initially increases slowly and then increases rapidly
<u>y = 2(1/2)^x</u>
y-intercept at (0, 2)
graph initially decreases rapidly and then decreases slowly
<u>y = (1/4)^x</u>
y-intercept at (0, 1)
graph initially decreases rapidly and then decreases slowly
