PLEASE HELP. I HAVE LIMITED TIME. 5. X to the fourth power plus the product of six and the square root of nine.
6. Fifteen plus eight cubed minus the sum of fourteen and six squared.
7. The product of three and fifteen minus nine plus the quotient of fifteen and three.
8. The product of seventeen and y, plus the square root of eighty-one minus the product of six and x minus four.

I think this is it, but i’m not sure about the last one

Use the symbol "^" to denote exponentiation.   write y = (x-9)^2 and y = (x + 9)^2.like y=x^2, the graphs of the two given functions are vertical parabolas which open upward.the graph of y=x^2 has its vertex at (0,0).   that of y = (x-9)^2 has exactly the same shape, but has its vertex at (9,0).   that of y = (x+9) has the same shape, but has its vertex at (-9,0).   the principle here is "horizontal shift."

Is there a picture for this
