(TIMED TEST) Use the graph of the function to estimate intervals on which the function is increasing, decreasing, or constant. Support the answer numerically. From the graph, it appears that: A function f(x) = -1/2 x^2 + x + 4 is decreasing for _. A function f(x) = -1/2 x^2 + x + 4 is increasing for _. The critical points is _.

step-by-step explanation:

its 512 because parenthesis and to the 2nd power is 512 so it will be 512

step-by-step explanation:

this can be solved first with pythagorean theorem, which tells us to square both legs of the triangle and sum it. this will be equal to the square of the hypotenuse.

the hypotenuse is the side "opposite" the 90 degree angle, which is x.

so we can write using pythagorean theorem,

simplifying:

to further simplify this radical, we need to use the property  

thus

the answer is option a you would get more money.it would be $250.

step-by-step explanation:

for option b 200/2=100=50% 100/2=50=25% 50/5=10=5% it would be $220
