Just replace x by 4 in the formula.
3(4) - 2 = 12-2 = 10.

y = 3x + 2x^2 + k where k is any number
3x * (x - 4) = 3x*x - 3x*4 = 3x^2 - 12x.
B- It is a many-to-one function

At x = 3, the value of F(x) = 3x + 2 is the value 11, which graphs to the point (3, 11).
The function f(x) = 3x + 2 can take any real value, so the question does not seem to make any sense.
graph G(x)=[x]-1
The range is the all the possible y-values for the function. f(x)=2-3x does not have any points where it is undefined because it is a linear function ( a line). The answer is all real numbers or (-infinity,infinity)
please elaborate your question
x^2 + 3x + 2/(-3x) - x^2 - 2=3x-2+2/(-3x)=3x-2-2/(3x)
If 2 divided by 3x it is equal to 2/3x
9x2 + 12x + 4 = 9x2 + 6x + 6x + 4 = 3x(3x + 2) + 2(3x + 2) = (3x + 2)(3x + 2) = (3x + 2)2
