2. a style of dance music marked by some of the features of jazz.
The graph of y = 2x+1 is a straight line. 1  When x increases, y increases twice as fast, hence 2x. 2  When x is 0, y is already 1.  So: y = 2x + 1.
Analyzing Linear and Exponential Functions. Linear. To graph a linear function, such as f(x)=2x+3, you first look at the y-intercept (3). Next, you see the slope (2x) and graph that.The line will be sloping upwards because the slope is positive, and will meet the y axis at 3, since that is the y intercept.It will look like this:Exponential. To graph an exponential function, such as f(x)=2^x, you plug in the x values and plot the points.he line will be sloping upwards because the slope is positive, and will meet the y axis at 3, since that is the y intercept.
