Consider f(x)=x2−4x+9 and g(x)=x+5, as shown below. ∘∘] (1) Use algebra to find where these two curves intersect.(start with letting f(x)=g(x)) (2) Represent the enclosed area as a definite integral. Write down the lower limit, upper limit, and the simplified integrand. (3) Use a calculator to compute the area of the shaded region. In (2), only need to provide lower/upper limits and integrand; in (3), by calculator, write down the command you use, without calculator, you integrate by hand.
