Which is the graph of f(x)=3(2/3)x?

anyanavicka [17]

we have that

$f(x)=3(\frac{2}{3})^{x}$

Step 1

<u>Find the y-intercept</u>

we know that

The y-intercept is the value of f(x) when the value of x is equal to zero

For $x=0$

$f(0)=3(\frac{2}{3})^{0}=3$

Point $A(0,3)$

Step 2

<u>Find the value of f(x) for $x=1$ </u>

$f(1)=3(\frac{2}{3})^{1}=2$

Point $B(1,2)$

Step 3

<u>Graph the point A and B to find the solution</u>

therefore

the answer in the attached figure

Lady_Fox [76]

Answer:

Combined volume of the two game systems $=416$ cubic inches

Step-by-step explanation:

Volume of a cuboid = length × breadth × height

Soham's video game system measures 8 inches long, 6 inches wide, and 2 inches tall.

So,

Volume of Soham's video game system = 8 × 6 × 2 = $96$ cubic inches

As Sean's video game system measures 1 inch longer on all sides,

the video game system measures $8+2=10$ inches long, $6+2=8$ inches wide, and $2+2=4$ inches tall.

Volume of the video game system = 10 × 8 × 4 = $320$ cubic inches.

Therefore,

Combined volume of the two game systems = $96+320=416$ cubic inches
