Q. graph of y=5(1.2)x is shown in the −plane. Which of the following characteristics of the graph is displayed as a constant or coefficient in the equation as written?
Identify Equation Components: The equation given is y=5(1.2)x. To understand the characteristics of the graph that are displayed as constants or coefficients, we need to identify each part of the equation and its role in the graph.The number 5 is the initial value or the y-intercept of the graph when x=0. This is because when x=0, y=5(1.2)0, and anything raised to the power of 0 is 1, so y=5×1, which is 5.
Interpret Initial Value: The number 1.2 is the base of the exponential function. This base represents the growth factor per unit increase in x. Since the base is greater than 1, it indicates that the graph represents exponential growth.
Understand Base Role: The variable x is the exponent in the equation, which represents the independent variable on the horizontal axis of the graph. The value of y depends on the value of x, and as x increases, y increases exponentially because of the base 1.2.
Explain Variable x: The constant 5 and the coefficient 1.2 are explicitly shown in the equation. The constant 5 is the y-intercept, and the coefficient 1.2 is the growth factor of the exponential function.
