$[-/5$ Points$]$

MY NOTES

$($a$)$ Write an expression for the function, $F(x),$ if it is known that $F^{\text{'}}(x)=e^{-x^2}$ and $F(0)=7.$ Give your answer using the form below. Hint: See example $5$ in section $6\mathrm{.}1$ of the textbook.

$($b$)$ Estimate the value $F(1)$ using the Left Hand Sum with $n=20.($Round your answer to three decimal places.$**)$

$F(1)$~~
