Which of the following polynomials corresponds to the subtraction of the multivariate polynomials 19x 3 + 44x 2 y + 17 and y 3 - 11xy 2 + 2x 2 y - 13x 3?
a. y 3 - 6x 3 + 33x 2y + 2x 2y + 17
b.20x 3 - y 3 + 33x 2y + 2x 2y + 17
c.31x 3 - 6x 3 + 44x 2y + 11x 2y + 17
d.32x 3 - y 3 + 42x 2y + 11x 2y + 17

y = 3x+4

step-by-step explanation:

to find the slope

slope = (y2-y1)/ (x2-x1)

    = (-8-4)/ (-4-0)

    = -12/-4

  = 3

using the slope intercept form of a line

y= mx+b

we know the slope is 3

we know the y intercept is 4 ( the point where it crosses the y axis or x=0)

y = 3x+4

f(x) is   are being squared

g(x) is   increasing by 2

h(x) is adding .25 each time

k(x) is taking the square root

f(x) and k(x) are exponential functions
