Question

Write an exponential function y=ab^x for a graph that includes (1, 15) and (0, 6).

Answer 1

\[y=a\times b^x\]
\[6=a\times b^0\]
\[6=a\times 1\]
\[a = 6\] so we know what a is, now we have to find b

Answer 2

\[15=6\times b^1\]
\[15=6b\]
\[b=\frac{15}{6}\] ans we are done

Answer 3

thank you :)
