Q. If y=9(31)x−4 is graphed in the xy-plane, which of the following characteristics of the graph is displayed as a constant or coefficient in the equation?Choose 1 answer:(A) y-intercept(B) x-intercept(C) Slope(D) The value y approaches as x increases
Identify Constants and Coefficients: Analyze the given equation y=9(31)x−4 to identify constants and coefficients.The equation is in the form y=A⋅Bx−C, where A is a coefficient, B is the base of the exponential function, and C is a constant.
Find Y-Intercept: Identify the y-intercept from the equation.The y-intercept occurs when x=0. Plugging x=0 into the equation, we get y=9(31)0−4, which simplifies to y=9(1)−4, and then to y=5. The y-intercept is the constant term in the equation that remains after the exponential part equals 1 (when x=0).
Determine Constant Term Meaning: Determine which characteristic the constant term represents.The constant term −4 in the equation y=9(31)x−4 represents the vertical shift of the graph, which is the value y approaches as x increases. This is because as x becomes very large, the term 9(31)x approaches zero, and the graph approaches y=−4.
Match with Options: Match the characteristic with the given options.The constant term −4 corresponds to the value y approaches as x increases, which is one of the given options.
