Only number 7. . i start school tomorrow

y = x² + 1

Step-by-step explanation:

Consider the differences in the y values

y : 1  2  5   10  17

      1   3   5   7 ← first differences are not constant so not linear

Consider the differences of the first differences

1   3   5   7

  2  2   2← second differences are constant

Because the second differences are constant the relationship is quadratic

The form of the relationship is

y = x² ± c ← where c is a constant

Substitute values of x into the relationship to find what is needed

x = 0 : y = 0² = 0 ← require to add 1 to obtain 1

x = 1 : y = 1² = 1 ← require to add 1 to obtain 2

x = 2 : y = 2² = 4 ← require to add 1 to obtain 5

x = 3 : y = 3² = 9 ← require to add 1 to obtain 10

x = 4 : y = 4² = 16 ← require to add 1 to obtain 17

Hence relationship is y = x² + 1

a line is an defined derm because it

a)contains an infinite number of points b) can be used to create other geometric shapes c)describes something that does not have width or depth d) is a term that does not have a formal definition. a line is an undefined term because it: contains an infinite number of points.
