21. Graph f(x) = (x and g(x)= 1 Vx on the same axes. 22. Describe g(x) as a transformation of f(x). What are the domain and
range
of each function?
23. Graph p(x) = Vx and g(x) = Vx+4 – 2 on the same axes.
24. Describe q(x) as a transformation of p(x). What are the domain and
range of each function?
25. Reason abstractly. Write a square root function that has a domain
of x > 7 and a range of y> 2. Use a graphing calculator to confirm that
your function meets the given requirements.

Girardo is using the model below to solve the equation . girardo uses the following steps: step 1 add 4 negative x-tiles to both sides step 2 add 1 negative unit tile to both sides step 3 the solution is which step could be adjusted so that gerardo's final step results in a positive x-value? in step 1, he should have added 4 positive x-tiles to both sides. in step 1, he should have added 3 negative x-tiles to both sides. in step 2, he should have added 4 negative unit tiles to both sides. in step 2, he should have added 1 positive unit tile to both sides.

Factor the following expression. 27y3 – 343 a. (3y + 7)(9y2 + 2ly + 49) b. (3y – 7)(9y2 + 2ly + 49) c. (3y – 7)(932 – 217 + 49) d. (3y + 7)(92 – 2ly + 49)

Can someone me with #s 8, 9, and 11. with just one of the three also works. prove using only trig identities.
