Q. The graph of y=12(0.25)x+1 is shown 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) x-intercept(B) y-intercept(C) Slope(D) The value y approaches as x becomes very large
Identify Characteristics: We need to identify which characteristic of the graph is directly represented in the equation y=12(0.25)x+1. Let's start by examining the equation and its components.
Find Y-Intercept: The y-intercept of a graph is the value of y when x is 0. To find the y-intercept from the equation, we substitute x with 0 and solve for y.y=12(0.25)0+1y=12(1)+1y=12+1y=13The y-intercept is 13, which is displayed in the equation as the sum of the constant term 1 and the coefficient 12 multiplied by (0.25)0.
No X-Intercept: The x-intercept is the value of x when y is 0. However, in the equation y=12(0.25)x+1, there is no x-intercept represented because the term +1 ensures that y is never 0 for any real value of x.
No Slope Represented: The slope of a graph is represented by the coefficient of x in a linear equation, which is of the form y=mx+b. However, the given equation is not linear; it is an exponential decay function. Therefore, there is no slope represented as a constant or coefficient in this equation.
Horizontal Asymptote: The value y approaches as x becomes very large is known as the horizontal asymptote. In the equation y=12(0.25)x+1, as x becomes very large, the term (0.25)x approaches 0, and the value of y approaches the constant term +1. This constant term represents the horizontal asymptote of the graph.
