Question

Graph the exponential function f(x)=-(2/3) .

To graph the function, plot the points on the graph with x-values -2,-1,0,1,and 2, draw all asymptotes.

Answer 1

You didn't copy the problem successfully. Your formula is corrupted.

Answer 2

Sorry it should be:

Graph the exponential function \[f(x)=-(\frac{ 2 }{ 3 })^{x} \] .

To graph the function, plot the points on the graph with x-values -2,-1,0,1,and 2, draw all asymptotes.

Answer 4

how do i plot this?

Answer 5

Make yourself a table of x and y values:

x y
-2 -(2/3)^-2
-1 -(2/3)^-1
0 -(2/3)^0
1 -(2/3)^1
2 -(2/3)^2

(you'll have to evaluate the expressions I wrote in the y column)

Plot the points on your graph. Draw a smooth curve through them.

Answer 6

Don't be worried if your graph looks different than @ikram002p's graph: he graphed \[y = (\frac{2}{3})^x\]not\[y = -(\frac{2}{3})^x\]

Answer 7

so for the points I have: -2, -2.25, -1,-1.5, 0,-1,1,-0.67, 2,-0.44. is that right?

Answer 8

Yes, here they are in both symbolic and numeric form:
\[\begin{array}{ccc}
x & y & y\\\hline\\
-2 & -\frac{9}{4} & -2.25 \\
-1 & -\frac{3}{2} & -1.5 \\
0 & -1 & -1. \\
1 & -\frac{2}{3} & -0.666667 \\
2 & -\frac{4}{9} & -0.444444 \\
\end{array}\]
