(a) 5
(b) log x as x>0
as x
(c) ln x as x ->co
(d) 4" as x ->-co
Expert Solution
Step 1
Since we only answer up to 3 sub-parts, we’ll answer the first 3. Please resubmit the question and specify the other subparts (up to 3) you’d like answered.
Answer(a): As x-> infinity , then 5^-x approaches 0.
Step 2
We know log 1=0 , when x < 1 then log x is negative number.
As, x-> 0^+ then log x goes to -infinity.
Answer(b): As x->0^+ the graph goes to extrem downwards (towards -infinity)
