Step-by-step explanation:

They forgot to reverse b

Step-by-step explanation:

-1 is supposed to be +1

-(b) +- (b^2 - 4(a)(c)

         2(a)

           OR

-(-1) +- ((-1)^2-4(1)(-30))

            2(1)

since we know that the two functions are equal, f (x) = g

(x), therefore when we equate the two equations the result should be similar to

3x = x – 4:

a. f(x) = 3x, g(x) = x – 4

equating the two functions:

3x = x – 4             (correct)

so we now got our answer (a)
