Writing Exponential Equations Given a Point and Y-intercept

Guided Notes

3 key concepts

  • 1

    The exponential equation is in the form y = abˣ, where 'a' represents the y-intercept.

  • 2

    To write an exponential equation given a point and y-intercept, first identify the values for x, y, and a.

  • 3

    After identifying x, y, and a, plug those values into the equation y = abˣ and solve for b, then write the final equation using the values for a and b.
