Final answer:
The equation y = 3(2ˣ) represents exponential growth. Graph B represents this equation with a y-intercept of 3.
Step-by-step explanation:
The equation y = 3(2ˣ) represents exponential growth, where the y-value is determined by multiplying 3 by 2 raised to the power of x. To determine the graph that represents this equation, we look for the y-intercept, which occurs when x = 0. Plugging in x = 0 into the equation, we get y = 3(2⁰) = 3(1) = 3. Therefore, the correct graph is Graph B, with a y-intercept of 3.
