Math Problem Statement

Graph this function:y=5|x|Click to plot the vertex first.

Solution

The given function is y=5xy = 5|x|, which represents a V-shaped graph due to the absolute value. The vertex of this function is at the origin, (0,0)(0, 0), since no horizontal or vertical shifts have been applied.

Steps to Graph:

  1. Plot the Vertex: The vertex of y=5xy = 5|x| is at (0,0)(0, 0). This is the starting point of the graph.

  2. Plot Additional Points: The absolute value function produces two linear parts, one for x0x \geq 0 and one for x<0x < 0. The slope for the positive part is 5, and the slope for the negative part is also 5.

  3. Direction of the Graph: For x>0x > 0, the graph follows y=5xy = 5x.
    For x<0x < 0, the graph follows y=5(x)y = 5(-x), which is equivalent to y=5xy = -5x.

  4. Shape of the Graph: The result is a V-shaped graph with steep lines due to the coefficient 5.

Vertex:

You can click to plot the vertex at (0,0)(0, 0).

Tip:

When graphing absolute value functions, the coefficient outside the absolute value affects the steepness of the lines, while constants inside the absolute value affect horizontal shifts.
