Answer:
I. D:
ii. R:
iii. Y-int:
Step-by-step explanation:
i) The given absolute value function is
The domain is all values of x that will make the function defined.
The absolute value function is defined for all real numbers.
The domain is all real numbers.
ii) The range is the values of y for which x is defined.
The given absolute value function is
This function has the vertex at and it is reflected in the x-axis therefore the vertex is the maximum point on the graph.
The y-value of the vertex is the maximum value on the graph.
Hence the range is
iii) To find the y-intercept, we put x=0, into the function to get;
The y-intercept is or (0,-6)
