Ineed an answer to 2. a and b and 3. a

The square of an odd number:

We're to conjecture, not do algebra, apparently.  1²=1, 3²=9, 5²=25, 7²=49, ...

We conjecture the square of an odd number is odd.

The product of two evens and an odd:

Again, we'll run some examples.

(2)(2)(1)=4

(2)(4)(3)=24

(4)(6)(5) =120

(4)(8)(1)=32

Conjecture: The product of two evens and an odd is a multiple of 4

Counterexample: The product of two fractions is never an integer

How about

3/4 × 4/3 = 1

answer: a and c are correct

step-by-step explanation:

the +5 is the vertical translation

the added negative symbol in front is the reflection over the y-axis
