Answer:
b. all real numbers
Step-by-step explanation:
The graphs of positive and negative x^2 parabolas will always have a domain of all real numbers. Even though you only have a portion of the graph and see a "restriction" on your domain values, it is incorrect to assume that the domain is limited to what you can see. As the branches of the parabola keep going up and up and up, the values of x keep getting bigger and bigger and bigger. Again, this is true for all + or - parabolas.

Answer:
1 and 2
Step-by-step explanation:
Answer:
use pythagorean's theorem; x=6
Step-by-step explanation:
a^2 + b^2 = c^2
a=length; b(x)=height; c= hypotenuse (longest side)
8^2 + b^2 = 10^2
64 + b^2 = 100 (subtract 64 from each side)
b^2= 36
6 x 6 = 36 so b=6
x=6
