These are how the graphs will look, they are color coded so have a look at the equations first.
Here u go, hope this helped
Answer:
5 point
Step-by-step explanation:
dividing the ratio
200/3+3+4=200/10=20
# of exercises
T 3 x 20=60
H 3 x 20=60
S 4 x 20=80
# of points
T60 x 5=300
H 60x 5=300
S 80 x 8=640
total points: 1240
So Helen recieved 5 points for each exercise completed
becaseu tom and helen have the same ratio
Domain is the numbers you can use
you can't use any numbers that make an impossibility like a negative square root or dividing by 0
set the denomenator equal to 0 to find what values of x make it 0
x^3-1=0
add 1 both sides
x^3=1
cube root both sides
x=1
domain is all real numbers except for 1
range is the numbers you get from inputing domaain
there is a vertical assemtote there so all bases are covered
range is how high and low y goes
domain is how far left and right x goes
domain is all real numbers except x=1
range is all real numbers
