Question

Algebra 2 help needed urgent !!!

Answer 1

11, 7, 3, -1, -5

Explanation:

The dependent variable y is often used interchangeably with the function value f(x). That is, we can usually presume that ...

y = f(x)

__

evaluate the function

To find f(x), put the value of x everywhere x appears in the function definition, and do the arithmetic. A calculator or spreadsheet can relieve some of the boredom of repetition. Here are a couple of examples.

f(-2) = -4(-2) +3 = 8 +3 = 11

f(-1) = -4(-1) +3 = 4 +3 = 7

time saver

You may notice that each increase of 1 in the value of x causes a decrease of 4 in the value of y. That means we can simply subtract 4 from the previous value of y to find the next one:

`\begin{array}c\cline{1-2}x&y\\\cline{1-2}-2&11\\\cline{1-2}-1&7\\\cline{1-2}0&3\\\cline{1-2}1&-1\\\cline{1-2}2&-5\\\cline{1-2}\end{array}`
