Determine a relationship between the x- and y- values. write an equation.
x =1 2 3 4
y = 4 5 6 7

The relationship here between the x and y values can be seen in an equation, y=x+3, since every y value is three more than its corresponding x-value. 

X^4 + 36x^2 = x^2(x^2+36)= x*x*(x+6i)(x-6i) mark me brainliest
