What is the domain and range?

If you shift the linear parent function, f(x)=x, up 13 units, what is the equation of the new function?

Write the expression as a single natural logarithm. 2 in a - 4 in y

What is the domain of the given function? {(3,-2), (6, 1), (-1, 4), (5,9), (-4, 0); o {x | x= -4,-1, 3, 5, 6} o {yl y = -2,0, 1,4,9} o {x|x = -4,-2, -1,0, 1, 3, 4, 5, 6, 9} o y y = 4,-2, -1, 0, 1, 3, 4, 5, 6, 9}
