The domain of a function is the set of values of x for which a value of y exists. In this case, the only way that a value of y would not exist is for a denominator to equal to zero. If this function is f(x) = 1/(x+1) + 5, then we must find the values of x for which the denominator (x+1) = 0, which is at x = -1.
Therefore the domain is all real numbers except x = -1. In interval notation this can be written as (-infinity, -1), (-1, infinity).
Answer:
f = 2x + 24/ 3
Step-by-step explanation:
Step 1: Divide both sides by x.
fx/x = 2/3 x^2 + 8x/x
f = 2x + 24/3
Every input(x) has only one output(y)
Emily and Marie can’t have the same birthday in this so it’s not a function
Answer:
8/0.56, which equals 14.2857142857, but rounded it would equal 14.3! I am not sure if this is correct but I tried!
Step-by-step explanation:
3n-5=-48-40n
Move -40n to the other side. Sign changes from -40n to +40n.
3n+40n-5=-48= -48-40n+40n
3n+40n-5=-48
Move -5 to the other side.
3n+40n-5+5=-48+5
3n+40n=-43
43n=-43
Divide by 43 for both sides
43n/43=-43/43
n=-1
Answer: n=-1
