This is for pre calc, chapter 2 functions Note: each square represents one unit.

1.Find the average change of the function between x=1 and x=4

2.what is the domain of this function? ( use interval notation or set notation)

3.what is the range of this function? ( use interval notation or set notation)

4.where is the function increasing?( if at all)

5.where is the function decreasing? ( if at all)

6.give the coordinates of any local minimum( write none, if none)

7. give the coordinates of any local maximum( write none, if none)

8.give the coordinates of global minimum( write none, if none)

9. give the coordinates of global maximum( write none, if none)

10. indicate whether the function is even. odd, or neither

This is for 15pts! please help!!​

step-by-step explanation:

< coa = 150 ( given)

as ba and bc are tangents

so oc and oa is perpendicular to cb and ab respectively because in circle normal passes through centre

so in quadrilateral oabc

< coa + < oab + < ocb + < abc = 360

150 +90+90 + < abc = 360

330 + < abc = 360

< abc = 360 -330 = 30

so < abc = 30

c. y = 1/4 x + 5

step-by-step explanation:

first, put the equation of the line on the graph into slope-intercept form

(y = mx + b):   y = -4x + 8

second, a perpendicular line has to have "an opposite/reciprocal slope" to the original slope. so, find the "m" value in your original equation (it's -4, right? )

original slope: m = -4   perpendicular slope: change the sign to its opposite and find the reciprocal ("flip" the number)

new slope is now positive (b/c the original slope was negative 4), and it's 1/4 (not the original slope of 4 or 4/1)
