(a) Write an expression for the function, F(x), if it is known that F'(x) = e"'2 and F(O) = 5 . Give your answer using the form below. Hint: See example 5 in section 6.1 of the textbook. F(X) = c + /XA(t) dt 6 C: 5 5: 0 'I A(l')= e_t2 J (b) Estimate the value F(1) using the Left Hand Sum with n = 20. (Round your answer to three decimal places.**) F(1) z 2.762 x ** You may need to use the numerical integration tool https://www.zweigmedia.com/RealWorld/integral/integral.html
