No it’s not a rational number
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:
7.
(x + 1)² = x² + 2x + 1
as the original function, but the turnaround is now (still at x = 0) at y = 1 instead of y = 0.
and the graph is "narrower". for x = 1 and x = -1, y = 4. for x = 2 and x = -2, y = 9
8.
= x² - 2
it is exactly the same graph, just 2 units down in y direction (the turnaround is at x = 0. y = -2).
9.
the right answer is D
Step-by-step explanation:
9.
the y values of +x values now become the same values for the -x values. and vice versa.
