Determine the range of the function graphed above. OA. (-4, 0]
OB. [0, 4]
Oc. (-00, 4]
OD. [4, 00)

Step-by-step explanation:

the range are the y values so must be [4,-∞) because if you look at the y-axis the highest value is 4 and the lowest goes to -∞

answer

d. 10

explanation

the distance from point y to wx is the height of the triangle.

using pythagoras theorem,

group similar terms to get,

this implies that,

take positive square root of both sides to get,

this implies that,
