To find the area of the curve subject to these constraints, we must take the integral of y = x ^ (1/2) + 2 from x=1 to x=4
Take the antiderivative: Remember that this what the original function would be if our derivative was x^(1/2) + 2
antiderivative (x ^(1/2) + 2) = (2/3) x^(3/2) + 2x
* To check that this is correct, take the derivative of our anti-derivative and make sure it equals x^(1/2) + 2
To find integral from 1 to 4:
Find anti-derivative at x=4, and subtract from the anti-derivative at x=1
2/3 * 4 ^ (3/2) + 2(4) - (2/3) *1 - 2*1
2/3 (8) + 8 - 2/3 - 2 Collect like terms
2/3 (7) + 6 Express 6 in terms of 2/3
2/3 (7) + 2/3 (9)
2/3 (16) = 32/3 = 10 2/3 Answer is B
Answer: 
Solving for variable x
Move all terms containing x to the left, all other terms to the right
<u>Add -17 to each side of the equation</u>
<u></u>
<u></u>
<u></u>
<u>Combine like terms: 17 + -17 = 0
</u>
<u></u>
<u></u>
<u></u>
<u>Combine like terms: -3 + -17 = -20</u>
<u></u>

<u></u>
<u>Divide each side by 2</u>
