g(x) = 3-2x2
h(x)=sq rt (x+5)
Domain and Range of the composite function, and the composite function itself.
I went at it this way;
Substitute it into sq rt (x+5), giving us;
sq rt (-8k2-8k+6)
Now I dont know if thats correct, or if I should divide all figures by 2, leaving us with;
and then the square root sign and exponent of 2 cancel out?
For domain, I don't know how to figure that out, I would assume you don't carry the original domain of h(x) which was x> or equal to -5
and range I would assume would have to be greater than or equal to 3 since that is the point at the parabola's vertex
Any help is appreciated everyone, this is my final unit of this course and I owe a lot of it to the helpful people on this forum, so thanks again!
