CPM Homework Help : GB8I Problem 9-48

Use the graph below to write an exponential equation in $f(x) = ab^x$ form.

Hint:

What part of the equation, $y = ab^{x}$ , can be easily calculated knowing the point $(0, 0.2)$ ?

More Help:

The second point is $(1, 1.6)$ . Use this point to calculate $b$ .

Increasing exponential curve, horizontal asymptote, at x axis, with highlighted point at (0, comma 0.2), & slope triangle, from that point to another point, labeled as follows: horizontal leg, + 1, vertical leg, + 1.4.
