Question

Find the domain and range of the given function: f(x)=(4)^x-5 +1

Answer 1

And domain and range for: f(x)=log2 (x-3) +4

Answer 2

for the posted question is the exponent (x-5) ?

Answer 3

yes it is above the 4

Answer 4

f(x)=(4)^x-5 +1
the first term must be > 0
so domain is all numbers > 1

Answer 5

- sorry thats the range!!

Answer 6

the range is always 1?

Answer 7

range is all numbers greater than 1?

Answer 8

no range is all numbers > 1
or (1, +infinity)

Answer 9

ok.

Answer 10

i still dont get it lol

Answer 11

well 4^(x-5) cannot be negative for real x nor can it be zero so it must be > 0
+1 makes 4^(x-5) + 1 > 1

Answer 12

the domain is the possible values of and here x can be any real value
domain is all real numbers
