The steps to enter the functions y 1 = 2 x 4 − 6 x 3 − 8 x 2 and y 2 = 2 x 2 ( x 2 − 3 x − 4 ) into a graphing calculator if 2 x 4 − 6 x 3 − 8 x 2 = 2 x 2 ( x 2 − 3 x − 4 ) .
The steps to enter the functions y 1 = 2 x 4 − 6 x 3 − 8 x 2 and y 2 = 2 x 2 ( x 2 − 3 x − 4 ) into a graphing calculator if 2 x 4 − 6 x 3 − 8 x 2 = 2 x 2 ( x 2 − 3 x − 4 ) .
The steps to enter the functions y1=2x4−6x3−8x2 and y2=2x2(x2−3x−4) into a graphing calculator if 2x4−6x3−8x2=2x2(x2−3x−4).
(b)
To determine
The expected result when the values of y1 and y2 are compared by TABLE feature of a graphing calculator if the functions are y1=2x4−6x3−8x2 and y2=2x2(x2−3x−4), and factorization 2x4−6x3−8x2=2x2(x2−3x−4).
(c)
To determine
To calculate: The values of y1 and y2 for values of x from 0 to 6 by TABLE feature of a graphing calculator if the functions are y1=2x4−6x3−8x2 and y2=2x2(x2−3x−4).
(d)
To determine
Whether the values of y1 and y2 for the functions y1=2x4−6x3−8x2 and y2=2x2(x2−3x−4) are same.
(e)
To determine
The meaning if the values of y1 and y2 is checked by the TABLE feature of a graphing calculator and their values are different.
