Write the equation for the function of the graph below

 (1)   (2) y = (x - 3)³

                    D: x ≥ -2  [-2, ∞)      D: -∞ < x < ∞ (-∞, ∞)

                    R: y ≥ -2  [-2, ∞)      R: -∞ < y < ∞ (-∞, ∞)

                    Inc: x > 2 (2, ∞)      Inc: (-∞, 3) ∪ (3, ∞)

                    Dec: never             Dec: never

Step-by-step explanation:

NOTES:

Domain is the x-values.

Range is the y-values.

From left to right: increasing when going up and decreasing when going down. The anchor and turning point are not considered to be increasing or decreasing.

step-by-step explanation:

if the four friends split the cost, p, of the pizza evenly, then each friend pays one-fourth of the cost of the pizza.

the expression is   or  

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
