Answer:
All real numbers
Step-by-step explanation:
To find the range of the function draw the graph of ths function (see attached diagram for details).
Since the base of the logarithm is the graph is increasing and passes through the point (1,0).
The domain of this function is
The range of this function is
or all real numbers.
Answer:
The values of k are 2/3 and -1
Step-by-step explanation:
Product of zeros = αβ= constant / coefficient of x^2 = 4/k
Sum of zeros =α+β = - coefficient of x / coefficient of x^2= -4/k
Given
Consider a= α and b= β
can be written as
if we add
in the above equation.
Putting values of αβ and α+β
The values of k are 2/3 and -1
