Help me plot 2* -1
To plot on a graph, need to know both x and y values.
I assume that -1 is an exponent.
Online "^" is used to indicate an exponent, e.g., x^2 = x squared.
2ex squered -4ex+5 meaning 2Xsquared minus 4Xplus5 how can i solve this
To plot the equation 2x - 1, we can use a Cartesian coordinate system.
First, let's determine some points on the graph by plugging in different x-values into the equation and solving for y.
Let's choose x = -2, -1, 0, 1, and 2 as our x-values.
For x = -2: y = 2(-2) - 1 = -4 - 1 = -5
For x = -1: y = 2(-1) - 1 = -2 - 1 = -3
For x = 0: y = 2(0) - 1 = 0 - 1 = -1
For x = 1: y = 2(1) - 1 = 2 - 1 = 1
For x = 2: y = 2(2) - 1 = 4 - 1 = 3
Now, we have the following points: (-2, -5), (-1, -3), (0, -1), (1, 1), and (2, 3).
Plotting these points on a graph, and drawing a straight line through them will give us the graph of the equation 2x - 1.
