Evaluate g(x) = 0.023x3 + 0.4x2 − 2.1x + 8.3 for x = 2 and x = 4.

Plug in 2 and 4 for every instance of x in the function g(x).

g(x) = 0.023x³ + 0.4x² − 2.1x + 8.3

g(2) = 0.023(2)³ + 0.4(2)² − 2.1(2) + 8.3 = 5.884

g(4) = 0.023(4)³ + 0.4(4)² − 2.1(4) + 8.3 = 7.772

5.884 and 7.772

this excerpt is taken from the book “we shall not be moved : the women’s factory strike of 1909 “ and is written by joan dash. it is the story of the great strike when almost 30thousand women working in factories in america formed a union to fight unsafe working conditions, long working hours and miserable wages.

question: which best states the author’s purpose for including this information in the text?

answer: to challenge the reader’s ideas about a historical event

since we know that the two functions are equal, f (x) = g

(x), therefore when we equate the two equations the result should be similar to

3x = x – 4:

a. f(x) = 3x, g(x) = x – 4

equating the two functions:

3x = x – 4             (correct)

so we now got our answer (a)
