y = 2x^2 - 8 \\ 2x^2 = y + 8 \\ x^2 = \frac{y+8}{2}  \\ x = \sqrt{\frac{y+8}{2}}  \\  f^{-1} (x)=\sqrt{\frac{x+8}{2}}

1. Draw an appropriate Venn diagram to depict each of the following sets. U = The set of integers. A = The set of even integers.
CaHeK987 [17]

The attached diagram represents the Venn diagram of the sets

<h3>How to draw the Venn diagram?</h3>

The sets are given as:

  • The universal set, U = The set of integers.
  • A = The set of even integers.
  • B = The set of odd integers.
  • C = The set of multiples of 3.
  • D= The set of prime numbers

From the above representation, we have the following highlights:

  • Set A and set B will not intersect, because no number can be even and odd
  • Set C and set D will intersect set A because they have common elements 6 and 2, respectively
  • Set C and set D will intersect set B because they have common elements 3 and 3, respectively

Using the above highlights, we can now draw the Venn diagram

See attachment for the Venn diagram
