Ineed , i don’t understand what i’m supposed to do

Step-by-step explanation:

For a, you need to plugin -9 into the equations inside the boxes and solve.

y = x^2 + 3, y = 9^2 + 3, y = 81 + 3, y = 84.

y = √x - 2, y = √9 - 2, y = 3 - 2, y = 1.

For b, It's only possible for the second equation to output 0, as for the first, it's impossible for x^2 to equal -3 and add to 3 to get 0. For the second equation you can plug in 4 to get 2 - 2, which gives 0.
