Question 1128799

Evaluate the function. (Round your answer to four decimal places.)
f(x) = −5e^x − 1, for  f(−2)

*I subsitiuted (-2) for x, which transformed the equation into -5^(-2)-1. The answer incorrectly resulted in .0080. Can someone demonstrate the correct method that should be used. thanks
<pre>You missed "e." This SYMBOL will be on some calculators, and is approximately 2.718281828.
Instead of what you have, it should be: {{{highlight_green(system(matrix(1,3, f(x), "=", - 5e^x - 1), matrix(1,7, f(- 2), "=", - 5e^- 2 - 1, "=", "- 1.676676416,", or, - 1.6767)))}}}
