Previous Shape of an Exponential Graph Next Vertical Graph Translations
  • Exponential graphs have a y-intercept of 1
  • The graph of y = 2^x has the typical shape of an exponential
  • As x increases, y increases and the graph gets steeper
  • The graph cuts the y-axis at (0, 1)
  • This is true for all values of k in exponentials y = k^x
  • Larger values of k result in steeper graphs
  • Substituting x = 0 into the exponential equation gives the y-intercept
  • Any number to the power of zero is one
