Determine what kind of functions the following graphs are. WILL MARK BRAINLIEST!!

The answer to your question is below

Step-by-step explanation:

Definitions

-An Odd function is a function whose graph is symmetric with respect to the origen.

-An Even function is a function whose graph is symmetric with respect to the y-axis.

For these graphs the answers are

a) Odd function

b) Even function

c) Even function

cosine

step-by-step explanation:

we have three similar triangles, because each has a right angle and shares an angle.   let's write the angles in order: opposite to short leg, long leg, hypotenuse.

cab similar to bad similar to cbd

or as ratios,

ca: ab: cb = ba: ad: bd = cb: bd: cd

we also know

ac = ad + cd

(ad+cd): ab: cb = ba: ad: bd = cb: bd: cd

(ad+cd)/cb=cb/cd

we have cb=6, ad=5 and seek x=cd.

we reject the negative root and conclude x=4

answer: 4
