Answer:

y = 120

Step-by-step explanation:

y = kx ur finding k

8 = k 3 get k alone by dividing both sides by 3 --> 8/3 = k

k = 8/3

Y = 8/3 45 now your finding Y when x is 45

Y = 120

to make sure do 120 = 8/3 45 should equal the same

Helppppppp pleaseeeee

Let's consider each of the options; 

A) The range is the values that y can be of the function f(x). We can see that no matter what x values you put in, f(x)>0. It will never be negative. Although, if you put (1/2)^2, you can get a y value of (1/4) so this statement is incorrect. 

B) It would have to put in the x or y value into the function and check. f(0)=(1/2)^0 

You know that anything to the zero-th power gives 1, therefore, this statement is correct. 

C) Again, if you put in a value such as (1/2)^2, you would be getting a number that is smaller than 1/2, so it isn't always increasing. 

D) Again, it is possible to input any value in x and you would still be getting a positive y-value, therefore, this statement is incorrect.

Hope I helped :)
