Answer:
x² - 4x + 12
Step-by-step explanation:
x=2+2.82843i
x=2−2.82843i
Answer:
Step-by-step explanation:
Assuming we want to find the equation (74,2) and (4,9)
This is an equation of a straight.
Let this equation be y=mx+b.
We substitute the slope and (4,9) to get:
We rewrite in standard form to get:
Answer:
B.
Step-by-step explanation:
Rate of change of y with respect to x, can be calculated using any two of the pairs of values of the table, say, (-2, 12) and (0, 3).
Rate of change =
Let,
Plug in the values
Rate of change =
