exponential growth
What exponential growth means in Mathematics A-Level, as defined for WJEC.
Definitions of exponential growth
Exam boards and our study guides word this term in slightly different ways. Learn the version your board uses.
Check what you remember
Read the wording for your board, then hide it and explain exponential growth in your own words. Rough notes are fine. This is a self-check, with no mark or grade.
Reference: WJEC
When a > 1 the function is strictly increasing, passes through the y-intercept (0, 1) and the point (1, a).
A model where k > 0, so the initial value y₀ at t = 0 increases without bound.
