Answer:
3. The correct option is A.
4. The correct option is C.
5. The correct option is C.
6. The correct option is B.
Step-by-step explanation:
3.
The given function is
The function approaches to ∞ as x approaches to -∞.
The function approaches to 0 as x approaches to ∞.
Therefore option A is correct.
4.
The given function is
The exponential function is in the form of
If a<0, then f(x) is a negative function and if a>0, then f(x) is a positive function.
If |b|>1, then f(x) is a increasing function and if |b|<1, then f(x) is a decreasing function.
Since a=-6<0 and b=5>1, therefore f(x) is a negative and increasing function.
Option C is correct.
5.
From the given graph it is noticed that the graph passing through the points (-1,-8) and (1,-2).
We have to find the slope of graph from -1 to 1.
Slope of function form -1 to 1 is
Therefore option C is correct.
6.
The y-intercept is 2 it means at x=0, the value of y is 2.
Since g(x) has y-intercept 2, therefore option B is correct.
