Q. The graph of the function y=x2 is shown. How will the graph change if the equation is changed to y=(1/4)x2 ?The parabola will become narrower.The parabola will move up 1/4 unit.The parabola will become wider.The parabola will move down 1/4 unit.
Compare Equations: Compare the two equations y=x2 and y=(41)x2 to determine the effect of the coefficient on the x2 term.The original equation y=x2 has a coefficient of 1 on the x2 term, which means the parabola opens upwards and is of standard width.The new equation y=(41)x2 has a coefficient of 41 on the x2 term, which is less than 1. This coefficient will affect the width of the parabola.
Effect of Coefficient: Analyze the effect of the coefficient (41) on the width of the parabola. A coefficient less than 1 (but greater than 0) on the x2 term will cause the parabola to become wider compared to the parabola with a coefficient of 1. This is because the y values increase more slowly as x moves away from the vertex, causing the parabola to spread out more.
Analysis of Width: Determine if there is any vertical shift in the parabola due to the change in the equation.Since there is no constant term added or subtracted from the equation, there is no vertical shift in the parabola. The vertex remains at the origin (0,0).
Vertical Shift: Conclude the effect of changing the equation from y=x2 to y=(41)x2. The graph of the function y=(41)x2 will become wider compared to the graph of y=x2. There is no vertical shift or narrowing of the parabola.
