Step 1.1

To find if the table follows a function rule, check to see if the values follow the linear form $y = a x + b$ .

$y = a x + b$

Step 1.2

Build a set of equations from the table such that $y = a x + b$ .

$130 = a (110) + b 110 = a (160) + b 100 = a (200) + b 90 = a (240) + b 80 = a (300) + b$

Step 1.3.1.1

Rewrite the equation as $a (110) + b = 130$ .

$a (110) + b = 130$

$110 = a (160) + b$

$100 = a (200) + b$

$90 = a (240) + b$

$80 = a (300) + b$

Step 1.3.1.2

Move $110$ to the left of $a$ .

$110 a + b = 130$

$110 = a (160) + b$

$100 = a (200) + b$

$90 = a (240) + b$

$80 = a (300) + b$

Step 1.3.1.3

Subtract $110 a$ from both sides of the equation.

$b = 130 - 110 a$

$110 = a (160) + b$

$100 = a (200) + b$

$90 = a (240) + b$

$80 = a (300) + b$

$b = 130 - 110 a$

$110 = a (160) + b$

$100 = a (200) + b$

$90 = a (240) + b$

Step 2.4.2

If the table has a quadratic function rule, $y = y$ for the corresponding $x$ value, $x = 110$ . This check does not pass, since $y = 0$ and $y = 130$ . The function rule can't be quadratic.

$0 \neq 130$

Step 3.4.1.2.2

Add $0$ and $0$ .

$y = 0$

Step 3.4.2

If the table has a cubic function rule, $y = y$ for the corresponding $x$ value, $x = 110$ . This check does not pass, since $y = 0$ and $y = 130$ . The function rule can't be cubic.

$0 \neq 130$

Step 3.4.3

Since $y \neq y$ for the corresponding $x$ values, the function is not cubic.

The function is not cubic

Step 4

There are no values for $a$ , $b$ , $c$ , and $d$ in the equations $y = a x + b$ , $y = a x^{2} + b x + c$ , and $y = a x^{3} + b x^{2} + c x + d$ that work for every pair of $x$ and $y$ .

The table does not have a function rule that is linear, quadratic, or cubic.
