Answer:

5 1/3

Explanation:

You want the value of the definite integral of (x² +5) on the interval [0, 1].

Integral

The power rule applies:

∫(x^n)dx = (x^(n+1))/(n+1)

This means the integral is ...


\displaystyle \int_0^1{(x^2+5)}\,dx=\left((x^3)/(3)+5x\right)_0^1=(1)/(3)+5

The value of y is 5 1/3.
