Note the rule

[tex]\\ \rm\bull\rightarrowtail y=36-18[/tex]
[tex]\\ \rm\bull\rightarrowtail y=18[/tex]
Answer:
36 -18
18
Step-by-step explanation:
This is slightly confusing, since the question says "find the y coordinate if x = -4" yet underneath if appears they want x = -6 !
If x = -6
Substitute -6 into the equation in place of x
⇒ y = 1 × (-6)² + 3(-6)
Apply the rule (-a)² = a² and a(-b) = -ab:
⇒ y = 1 × (6)² + -3×6
⇒ y = 1 × 36 + -18
Using order of operations, carry out the multiplication first:
⇒ y = 36 + -18
Then the addition (subtraction)
⇒ y = 36 - 18
⇒ y = 18
