Answer:

y = 5-\sqrt{x}

Step-by-step explanation:

Note that the graph shown is a transformation of the parent function

y = \sqrt{x}

The main function cuts the x-axis at x = 0 and has no negative values of y. In addition, the main function is always growing.

Note that the function shown is decreasing and intercepts the y-axis at y = 5.

Therefore, the graph of the main function has been reflected on the x-axis and displaced 5 units upwards.

If we do y = f(x) then to reflect the main function on the  x-axis and move it upwards 5 units we make the following transformation

y = -f(x) + 5.

Then the graphed function is:

y = 5-\sqrt{x}

Answer:

f(x) = -logx + 4.

Step-by-step explanation:

y = -log x  approaches  the point (0, 1)  but this approaches (0, 5)

Looks like the graph of - log x + 4.

Help ASAP!!!!<br> Which statement about the graph of the function y=(1/3)x are true?
mafiozo [28]

Answer:


Step-by-step explanation:

1) False:  The function is decreasing (because the base, 1/3, is between 0 and 1).

2) True:  The function is decreasing (see #1, above)

3) False:  There is no x-intercept.

4) True:  If x is 0, then y = (1/3)^0 = 1.

5) False:  the range consists of the set of all real numbers greater than zero.
