Answer:
i)D:
ii)R: 
iii) Y-int:(0,-1)
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 all y-values that will make x defined.
The given function,
.
has vertex at, (-2,-3) and opens upwards.
This implies that, the minimum y-value is -3.
The range is 
iii) To find the y-intercept substitute x=0 in to the function.
.
.
.
.
The y-intercept is (0,-1)

Answer:
radius is half of the diameter
42/2= 21
the radius is 21 cm
Step-by-step explanation:
Answer:
Option 1: y + 5 = ½(x - 2)
Step-by-step explanation:
First, you need to find the slope. the formula to find the slope from two points is
and if you plug in the points it will be
which is
.
point-slope form is
. m is slope and x₁ and y₁ is (2, -5).
plugging in the numbers will be y + 5 = ½(x - 2)
