у Which function represents the graph of y = 10(4)" ? 20 18 f 16 114 Og 12 0 h 10 h 8 f Оj j 4 g 2A 5 -4 -3 -2 -1 1 2 -2 1 2 3 4 5 6

Answer 1

$\text{The graph }y=10(4)^x\text{ has a y-intercept of}$

Substitute x = 0, to find y-intercept.

$\begin{gathered} y=10(4)^x \\ y=10(4)^0 \\ y=10(1) \\ y=10 \end{gathered}$

By inspection of the four graphs, the graph with a y-intercept of y = 10 is graph g.

Therefore, graph g represents the equation y = 10(4)ˣ.
