Graph each absolute value function. state the domain, range, and y-intercept.

i) D: All real numbers

ii) R:

iii) Y-int:(0,0)

Step-by-step explanation:

i) The given absolute value function is;

The absolute value function is defined for all real values of x.

The domain is all real numbers

ii) The range is the values of y that will make x defined.

The given function has vertex at the origin, (0,0) and it is reflected in the x-axis.

This means the function will open downwards.

The maximum y-value is therefore 0.

The range of the function is

iii) To find the y-intercept, put x=0 into the function to get;

The y-intercept is (0,0) or b=0

See attachment for graph.

add all the numbers and check the ones place.

the answer is 486. as the ones place is more than 4, the estimation will be the next 10 ie, 490

2nd one in the first row is correct
