The graph of f(x) = x2 was transformed to create the graph of g(x) = 4x2. Which of these best describes this transformation? OF. The graph will become narrower.
O G. The graph will become wider.
O H. The graph will shift 4 units up.
O J. The graph will shift 4 units to the right.

answer: .64

step-by-step explanation

set up the formula for standard deviation for this set of numbers, then simplify

probably .5

i can on others if necessary.

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
