Question 251492: 1. Evaluate the exponential equation for three values of x greater than -4, three values of x smaller than -4, and at x = -4. Show your work. Use the resulting ordered pairs to plot the graph;State the equation of the line asymptotic to the graph (if any). y=3^x=4+1
2. Evaluate the logarithmic equation for three values of x that are greater than -1, three values of x that are between -2 and -1, and at x = -1. Show your work. Use the resulting ordered pairs to plot the graph; State the equation of the line asymptotic to the graph (if any).
y = ln(x + 2)

You can put this solution on YOUR website! Let's take one question at a time.
1. Evaluate the exponential equation for three values of x greater than -4, three values of x smaller than -4, and at x = -4. Show your work. Use the resulting ordered pairs to plot the graph; State the equation of the line asymptotic to the graph (if any). Maybe you mean this? y=3^x+4x+1
make a table:
X: -1 . . . -2 . . . -3 . . . -4 . . . -5 . . . -6 . . . .-7
Y: -2.66 . . -6.88 . -10.96 . -14.98 . -19 . . -23 . . . .-27.
If this is not the correct formula, then you can use excel.

2. Evaluate the logarithmic equation for three values of x that are greater than -1, three values of x that are between -2 and -1, and at x = -1. Show your work. Use the resulting ordered pairs to plot the graph; State the equation of the line asymptotic to the graph (if any).
y = ln(x + 2)
make a table:
X: -1.75 . . . -1.5 . . . -1.25 . . . -1 . . . 0 . . . .1 . . . 2
Y: -5.85 . . .-4.81 . . .-3.75 . . . -2.66 . .2 . . . 8 . . . .18
There is a vertical asymptote at x = -2.
