5short Q&A pairs drawn directly from our worked dot-point answer. For full context and worked exam questions, read the parent dot-point page.

What is the exponential graph y equals a to the x?

Show answer

For a base

a > 1

, the graph of

y = a^x

Show answer

For base

a > 1

, the graph of

y = \log_a x
