need calc help plz

<p>Can someone help me with calculus? If you had a function that is shaped like the one below. Don't pay attention to the other stuff, I am just focusing on the shape of the function. If you are asked to find the integral over the interval 0 to 5, but you don't know the equation of the function, then how do you do this? </p>

<p>an integral of a function just represents the area under the curve. Thus just take the area of the geometric shapes relative to the x-axis.</p>
