Answer:

A) slope of f(x) = 3 , slope of g(x) = 7

B) y intercept of f(x) is 0 and g(x) is 2

So g(x) has greater y intercept

Step-by-step explanation:

Lets find equation of f(x) using the given table

LEts take two points from the table (0,0) (1,3)

$slope = \frac{y_2-y_1}{x_2-x_1} = \frac{3-0}{1-0} = 3$

we use equation y=mx+b

where m is the slope and b is the y intercept

we got m = 3, we use (0,0) and find out b

y=mx+b

0 = 3(0) + b

so b=0

So equation for f(x)= 3x +0

slope =3 and y intercept = 0

For equation g(x) = 7x +2 , slope = 7 and y intercept = 2

Answer:

$2x^2y[x^{2}y^{2}-6xy-4]$

Step-by-step explanation:

we have

$2x^{4}y^{3}-12x^3y^2-8x^2y$

Factor $2x^2y$

$2x^2y[x^{2}y^{2}-6xy-4]$
