4(2x+4z) when x= 3 y= 2 z= -2

4x^2 + y when x= 3 y= 2 z= -2

2(x^2 + (y-2))

correct answer:

b.(19,-2)

you already gave the answer

bfgbh bhf gfdzf bhgfrdfgbn cvdgsytrghvn ncvhgfdtrseawa hgdrsxcvbgfrewq

step-by-step explanation:

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)
