Which of the following statements are true? Check all that apply.

In general, multiplying a function by some constant k will stretch its graph vertically by a factor of k if k>1, or shrink its graph vertically by a factor of k if k<1. In this case, k=2>1, so statement A is true.

The function only accepts nonnegative inputs (so its domain is x>=0), and its outputs span all the nonnegative real numbers (range y>=0). This is also true of so statement C is also true.

false

step-by-step explanation:

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,
