Identify Domain: Identify the domain of y=3⋅2x. Since the function involves an exponential term 2x, which is defined for all real numbers, the domain is all real numbers.
Identify Range: Identify the range of y=3⋅2x. The exponential function 2x takes positive values for all x, and multiplying by 3 scales these values but keeps them positive. Therefore, the range starts from the smallest value, 0 (not included), to infinity.
Horizontal Asymptote: Determine the horizontal asymptote of y=3⋅2x. As x approaches −∞, 2x approaches 0, and thus 3⋅2x approaches 0. Therefore, the horizontal asymptote is y=0.
Find x-Intercept: Find the x-intercept of y=3⋅2x. Set y to 0 and solve for x: 0=3⋅2xDividing both sides by 3 gives 0=2x. This equation has no solution because 2x>0 for all x. Thus, there is no x-intercept.
Calculate y-Intercept: Calculate the y-intercept of y=3⋅2x. Set x to 0 and substitute into the equation:y=3⋅20=3⋅1=3Thus, the y-intercept is (0,3).
Analyzing End Behavior: Analyze the end behavior of y=3⋅2x. As x approaches infinity, 2x approaches infinity, and thus 3⋅2x also approaches infinity. As x approaches −∞, 2x approaches 0, and thus 3⋅2x approaches 0.
