You need to change the sign of all terms of g(x) and then combine the like terms and simplify your answer.
Step-by-step explanation:
Since the functions f(x) and g(x) are missing in the question, I will explain it with my own example and you can solve it with your functions.
Let f(x)= 2x^2+3x+4
and g(x) = 4x^2+9x-6
We need to find f(x)-g(x)
Solving:
f(x)-g(x)=2x^2+3x+4-(4x^2+9x-6)
f(x)-g(x)=2x^2+3x+4-4x^2-9x+6
f(x)-g(x)=2x^2-4x^2+3x-9x+4+6
f(x)-g(x)=-2x^2-6x+10
So, you need to change the sign of all terms of g(x) and then combine the like terms and simplify your answer.

Y - y1 = m(x-x1)
y - 7 = -3/2(x + 6)
I am 100% sure the answer is a.4
Because it was (2,3) then became (8,12)
2*4= 8 and 3*4= 12
The numbers 2 and 3 were multiplied by 4 to get 8 and 12
