Answer:
1. No
2. yes
3. yes
4. yes
Step-by-step explanation:
1. 2×3=6, 7×3=21 (The product of two (or more) prime numbers cannot result in another prime number. By definition, a prime number is a number that is divisible by 1 or itself - multiplying two or more primes together will always yield a number divisible by 1, itself and the prime numbers multiplied together to achieve it.
2.When you multiply an integer (a “whole” number, positive, negative or zero) times itself, the resulting product is called a square number, or a perfect square or simply “a square.” So, 0, 1, 4, 9, 16, 25, 36, 49, 64, 81, 100, 121, 144, and so on, are all square numbers.
3. 1×3=3, 3×5=15 (odd numbers are not divisible by 2)Therefore, every prime number other than 2 is an odd number
4. 2×4=8, 6×8=48

Answer:
the graph of y=x^2-4x is parabola as shown in the image
Step-by-step explanation:
The graph of by drawing the line y=x-4
so this gives us that the line y=x-4 satisfies the equation
To get points put y = x - 4 in the equation
so we get x -4 = x( x- 4)
x =1 and x - 4 = 0
from here we get x = 1,4
now put these values in y = x -4
From here we get y = -3,0
so the points are (1 , -3) and ( 4 , 0)
Plot these on graph and we get the straight line .
For equation
As we know it is of type of parabola with shifted centre.
