Answer:
Domain: 
Range: ![[0,4]](https://tex.z-dn.net/?f=%5B0%2C4%5D)
Step-by-step explanation:
<u>Domain</u>
We can see that the piecewise function starts at x=-2, which is included, and ends at x=1, which isn't included. To represent the x-values that lie in between these two endpoints, you would write . Brackets show that one endpoint is included while parentheses show that one endpoint isn't included.
<u>Range</u>
Following this logic, the range has its y-values go from 0 to 4 with both endpoints included if you were to trace the function. Thus, your range would be .
I don't know if this will help but I found this on YAHOO!
Answer: Domain of definition of a function is the set of numbers which the variable attains and for which the function is defined.
Step-by-step explanation:
f(x) = sqrt (5x-10)
Here x can have value equal to any real number >=2 because if x attains value less that 2, 5x-10 becomes negative and sqrt(5x-10) has no real value.
therefore the domain of the function f(x) is (2, infinity) inclusive of 2.
Answer:
2.57142857143
Step-by-step explanation:
5w + 9z = 2z + 3w
2w + 9z = 2z
2w = -7z
w= -7/2z or w= -3.5z
Step-by-step explanation:
90 nickels = 5*90=450=450/100=$4.5,
16 dimes=16*10=160=160/100=$1.6
16 quarters = 25*16=400=400/100=$4
7 fifty-cent pieces = 7*50=350=350/100=$3.5
Total dollars = 4.5+1.6+4+3.5=$13.6
Explanation : Hope it helps you Kenzee..
just correct me if I'm wrong..
