Which statement is true about the function f(x)= - square root of x?

It has the same range but not the same domain as the function .

Step-by-step explanation:

Recall the domain of the function is all x values which input into the function and give an output. The outputs or y values are called the range. To find the domain and range, graph the function and look at where it is on the coordinate plane.

starts at (0,0) and curves upward and towards the right. Its domain is and its range is .

starts at (0,0) and curves downward to the right. Its domain is still but its range is negative numbers or .

starts at (0,0) and curves downward to the left. Its domain is negative x values or and its range is negative values or .

This means the two functions have the same range but different domains.

c.35

step-by-step explanation:

8+13=21

21+8=29

29+6=35

a 4/6 = 9/12   not proportional

step-by-step explanation:

to find which are not proportional, we can use cross products

if it is true, they are proportional.   if it is not true, they are not proportional.

a 4/6 = 9/12

4* 12 = 6*9

48 = 54

not this is not proportional  

b 2/3 = 12/18  

2* 18 = 3 * 12

36 = 36

this is proportional

c 5/4 = 10/8  

5*8 = 4*10

40 = 40

this is proportional

d 7/5 = 35/25

7*25 = 5 * 35

175 = 175

is proportional
