Suppose that the graph of a function f is known. Then the graph of y equals=f(xminus−2) may be obtained by a shift of the graph of f a distance of 2 units.

For what values of the variable x is the expression square root of 7x+14+ square root of 7-x a real number?

Worth 100 points need the answers asap first row -x^2 2x^2 (x/2)^2 x^2 x is less than 2 x is greater than 2 x is less than or equal to 2 x is greater than or equal to 2 second row -5 -5/2 4 5 •2 is less than x& x is less than 4 •2 is less than or equal to x & x is less than or equal to 4 •2 is less than or equal to x& x is less than 4 •2 is less than x& x is less than or equal to 4

Cos^2x+cos^2(120°+x)+cos^2(120°-x)i need this asap. pls me
