Straight-line graphs of logarithmic and exponential functions Watch this video to learn about straight line graphs of logarithmic and exponential functions.

Find what needs to be added to the left-hand side (LHS) of the new equation to give the equation of the graph already drawn. 2 x 2 + 2 x 8 = 0 x + 2 2 x 2 + x 6 Draw this straight line.

For example, in the right hand graph of Figure 2 is a population of Paramecium growing in a laboratory culture. The pattern of growth is very close to the pattern of the exponential equation.
