The equation contains a binomial which is multiplied by itself.

(x - 2)(x - 2)

Use FOIL (first outside inside last) to expand.

(x^2 - 4x + 4) + 6

Remove brackets and simplify

y = x^2 - 4x + 10

TiliK225 [7]

Answer:

1. x > 17

Step-by-step explanation:

When the point on the graph is an open circle you are going to be using < or > as an open circle means greater than or less than

Immediately we can eliminate number 3 and 4

When the line is going in the direction of the right than the inequality sign will face the variable (x)

the numbers are getting larger meaning that x is greater than the constant (17)

Hence, your answer is x > 17

Extra notes:

when the point on the graph is a closed circle ( filled in ) then you will use ≤ or ≥ as a closed circle means greater than or equal to or less than or equal to
