A cosine function has a period of 4, a maximum value of 20, and a minimum value of 0. The function is a not a reflection of its parent function over the x-axis. Which function could be the function described?

f(x)=10cos(2x)−10

f(x)=−10cos(2x)+10

f(x)=−10cos(π2x)+10

f(x)=10cos(π2x)+10

the law of definite proportions states samples of a compound will always contain the same proportion of elements by mass. in other words, a given compound will always contain the same elements in the same proportions by mass.the law of multiple proportions states when two elements combine with each other to form more than one compound, then the weights of one element that combine with a fixed weight of the other are in a ratio of small whole numbers.
