Suppose that the functions f and g are defined for all real numbers x as follows.
f(x) = x+3
g(x) = 4x2
Write the expressions for ( g)(x) and (f+g)(x) and evaluate (f-)(-3).

i think it might be a but you might want a second opinion

9x

the image is given below

since the options are not given so we draw it from the equation

the given equation is

y = (x-1) (x+4)

y = y² + 3x - 4

the above equation is a quadratic equation which will have two roots. if we draw the graph for it, it will look like this
