Domain is all real numbers
range
hmm
we know that x^2=a positive number
then multiply it by that negative -3
therefor the range is going to be mostly negative
if we make the x-5 equal to zero, then there is no negative, so
wher x=5, then f(5)=0+4=4
the highest positive number you can get is f(5)=4
so therfor
domain=all real number
range is x≤4
Answer: 1.2 10x ^3
Step-by-step explanation:
Hey there!
The answer to your question is 
Write the equation
Distribute -2
Combine like terms
Add 10 to both sides
Divide both sides by -11
Hope it helps and have a great day!
Assuming that their exam success is independent then
P(both fail) = 1/4 x 2/5 = 2/20 or 1/10
