graphing e

[kimbero5]

how would i attepmt to graph the equation y=e^-(x+3) or even just plot it...so confused please help!!!!!!

Pick a value for x. Plug in it. Simplify to find the corresponding value of y. Plug the expression into your calculator to obtain a decimal approximate. Graph the (x, approx y) dot.

Repeat.

Sketch the line.

Hello, kimbero5!

How would i graph the equation y = e^-(x+3)
.

They expect you to be familiar with the graph of: y = e^x . . . Let's call it "G".
. . And they expect you to know what the "modifications" do to the graph.

In general, y = e^x-a looks like "G", but moved <u>a</u> units to the right.

Also, y = e^-x looks like "G", but "flipped" over the y-axis (a left-right reflection).


Your graph is: y = e^-(x+3)
. . In the parentheses, we have: x - (-3)
. . We have "G", moved 3 units to the <u>left</u>.
. . Sketch that graph.

Then the exponent has a "minus".
. . Your graph is reflected over the y-axis.
. . Sketch that graph.

And <u>that</u> is your answer.
