So anyone know how to do these

1) A

2) B

Step-by-step explanation:

The formula of rate of change from a certain number to another is

f(b) - f(a)

b - a

(i tried making a fraction if u couldnt tell)

Now substitute the values of x into the equation

(3*(-1) + 2) - (3*(1) +2)

           -1 - 1

now combine everything together:

(-3+2) - (3+2)

        -2

-1 - 5          -6         3

  =   =

 -2             -2

now do the same for the second question

(0^2 + 3) - (3^2 + 3)       (3 - 12)         -9          3

   =    = =             (answer choice B)

       0 - 3                           -3             -3

  or
