Answer: C. g(x) = x^4 - x^2 + 0.5</h3>
Why is this?
We start with x^4 - x^2, which is the original f(x) function. Adding some number to this result will increase the y coordinate of any point on the f(x) function. This is because y = f(x). The only thing that matches is choice C, where we shift the graph up 0.5 units. We say that g(x) = f(x) + 0.5
Choice D goes in the opposite direction, and shifts the graph down 0.5 units.
Choices A and B shift the graph horizontally to the right 0.5 units and to the left 0.5 units respectively.
If jenn has 13 fewer marbles than marty and we know she has 20 marbles, you would add 13 to 20 (33) to find how many marbles marty has. the equation would be 13+20=33 (or any variable depending on the context of the question.)
Important: indicate exponentiation with " ^ "
Thus, x = ( y - 4 )2 + 27 becomes <span>x = ( y - 4 )^2 + 27
This can be re-written as x = y^2 - 8y + 16 + 27, or x = ay^2 - 8y + 43. This is the equation of the parabola in standard form x = ay^2 + by + c.</span>
For this case we have the following functions:

We must find:
By definition we have to:

So:

Thus, we have to:

So, the value is -169

Option A
Answer: D’Andrea
Explanation: 93/3 = 31
176/4=44
215/5= 43
111/3= 37
44 is greater than 31, 43, and 37 therefore D’Andrea does the most sit-ups per minute.
