On a piece of paper, use a protractor to construct right triangle def with de=4 in. , m∠d=90° , and m∠e=45° .

what statement is true about the triangle?

df=4 in.

df=2 in.

ef=4 in.

ef=7 in.

g(x) is the negative form of f(x)? because whenever its the negative form it reflects its self over the x axis. idk if this is right though.

step-by-step explanation:

answer:     true

step-by-step explanation:

a function could be identified in 3 ways either on a chart,graph, or ordered pairs. first a function is that each point has its own. the rule is that there can be many x's to one y but there can not be 2 x's at different y's. so on a graph when you put a straight line through the y's there should be one dot only to be a function.
