Question

OK GUYS I WOULD LIKE SOMEONE TO PLUG IN THE VALUES FOR ME PLEASE FOR X TO MAKE THIS TRUE SO I CAN GRAPH THE EXPONENTIAL GRAPHS. SO Y=-4+ SQAURE ROOT X+2 SO AT LEAST 4 X VALUES TO MAKE THIS TRUE

AND FOR THIS ONE PLEASE:Y=2+SQUARE ROOT OF X+1 AT LEAST 4 X VALUES THAT MAKE THIS TRUE SO I CAN PLOT IT ON THE GRAPH

Answer 1

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!!

Answer 2

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)
