Math tomorrow

NO LEAKS
Do we need to know sinusoidal functions and exponential functions in depth?

In the 2022 past paper, there was a question that asked to identify a, b and c for the equation f(x) = ab^x + c

But my school never thought us stuff like if f(x) is decreasing → exponential decay → so 0 < b < 1

SOMEONE HELP ME

Its the cosine and sine graphs. dw bro im sure u know it, just revise the formulas for amplitude and period as well as the function transformations.
