Answer:
we see that we have some nasty sqrt signs
try to use x values that yield perfect squares inside the sqrt sign like 1,4,9,16, or ones that make the inside 0
first one
y=-4+√(x+2)
try some nice values for ease of graphing
ok so try x=-2
y=-4
(-2,-4)
x=-1
y=-3
(-1,-3)
x=-1
y=-3
(-1,-2)
if x=7
y=-1
(7,-1)
if x=14
y=0
(14,0)
so we have
(-2,-4)
(-1,-3)
(2,-2)
(7,-1)
(14,0)
second one
y=2+√(x+1)
if x=-1
y=2
(-1,2)
if x=0
y=3
(0,3)
if x=3
y=4
(3,4)
if x=8
y=5
(8,5)
we have
(0,3)
(-1,2)
(3,4)
(8,5)
first one
y=-4+√(x+2)
so we have
(-2,-4)
(-1,-3)
(2,-2)
(7,-1)
(14,0)
second one
y=2+√(x+1)
(0,3)
(-1,2)
(3,4)
(8,5)
Answer:
First question do u have a graphing calculator?? If so, go to the y= menu and type in 2+ (2nd x^2) square root of x+1then hit 2nd and then graph find any coordinate pair you want or just hit the graph button and look at the exponential graph Keep in mind I am explaining the steps to take on a Texas Instruments TI84 plus CE calculator Good luck!!
