H(x) = x2 + 3. is h-1 a function and why/why not?

No, the inverse does not pass the vertical line test

Step-by-step explanation:

Taking the inverse of an equation is fairly simple. Flip the x and y variables, and solve for y. When we do this, we get Y = root(x-3). Now, every time you take the square root of something, note that there are two possibilities (because of the plus/minus sign). This means that every value of x will result in two different answers because there are calculations of two values of y for one value of x. Then, one input will have two different outputs.

i would have to say it is c.

homozygous. one is homozygous, while two is heterozygous.
