Question

Which is the graph of the function y=—3(2)^x

Answer 1

Answer:

option D

Step-by-step explanation:

The given function is

$y = - 3( {2}^{x} )$

This is the graph of an exponential growth function that has been reflected over the x-axis.

The y-intercept is when x=0.

We get,

$y = - 3( {2}^{0} ) = - 3$

From the diagram, the correct graph is D
