A student tried to multiply two binomials. Their work is shown below: Step 1: (2x - 3)(x - 2)
Step 2: 2x (x - 2) – 3(x - 2)
Step 3: 2x2 — 4x - 3x - 6
Step 4: 2x2 – 7x - 6
In which step did the student make the first error?

step-by-step explanation:

once you graph it hit 2nd (the blue button) and graph

that takes you to a table of coordinates

on the left is x coordinates and on the right is y coordinates and an empty box

(you may have to scroll up/down in order to get ( x, 0)

yes

yes yes yes

the domain of a function is the set of input values, x , for which a function is defined. the domain is shown in the left oval in the picture below. the function provides an output value, f(x) , for each member of the domain.
