Key concepts
3 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.
