Graph the function f(x) = sin (x) - 2

(0.-2) (90,-1) (180,-2) (270,-3) (360,-2)

Step-by-step explanation:

You need 5 points to sketch this function

Take:

x=0, 90, 180, 270, 360

Find y values on the calculator

x=0, y= sin(0)-2 = -2

x=90, y= sin(90)-2 = -1

x=180, y= sin(180)-2 = -2

x=270, y= sin(270)-2 = -3

x= 360 y= sin(360)-2 = -2

(0.-2)

(90,-1)

(180,-2)

(270,-3)

(360,-2)

if x decreases by 4 then y increases by 10
