If you can help that would be great! The Function is f (x) = sqrt( 8x + 8 ) Then (f) is in the domain of (x) provided x>or equal to ??????????

can you rewrite the problem? the way it is in the ....book Im assuming....

  • amistre64
if anything, I would assume that it is asking for the domain of f(x).. but I am unclear with what you write here.

if so, the sqrt function can only have values equal to or greater then zero in it, any "x" that you use will have to be limited to values that make the expression equatl to or greater than 0.

yes its the domain of f(x) sorry

..then we can figure out the bad "x" values by doing this: 8x +8 >=0 8x >= -8 x>= -8/8 x>= -1 the domain for f(x) is then; all values of x that are greater than or equal to -1. or written in notation: [-1,inf)
