Use the left-hand rule to estimate the area under the graph of y = (x + 1)2 – 1 for values of x from 0 to 3.

11 square units

Step-by-step explanation:

Using the left-hand rule to estimate the area under a graph y = f(x) between the interval x = a to x = b is given by

.......... (1)

{Where n is the number of rectangles we want to make the area under curve.}

Now, in out case a = 0 and b = 3 and ....... (2)

Let us assume that  n = 3, then there will be 3 rectangles.

Therefore, from the equation (1), we can write

⇒ = 11 square units

{Since we have from equation (2), f(0) = 0, f(1) = 3 and f(2) = 8} (Answer)

im pretty sure it would be 5 am, hope that , and give brainliest and guys if this is right then press the button and give 5 stars
