Question

Choose the correct graph of g(x)=-4*(1/2) the power x +1

Answer 1

Is the equation g(x)=-4*(1/2)^(x+1) ?

I'll use y=-4*(1/2)^(x+1)

Explanation:

See attached graph

Use the free online DESMOS app to either plot the entire equation, or to plot individual points for a selected number of x values.

=============

For example: Pick several values of x and calculate the resulting g(x). Plot the x and result (y) as ordered pairs on the graph.

X Y Ordered Pair

-5 -64 (-5, -64)

-3 -16 (-3, -16)

0 -2 (0, -2)

2 -(1/2) (2, -1/2)

5 - (1/18) (5, -1/18)

10 -(1/512) (10, -1/512)
