What function is graphed below?

option (A) y =

Step-by-step explanation:

Since the given graph represents a parabola passing through origin so equation of the parabola will be

Either y = or y =  

y = 2x³ or y = -2x³ not a graph a parabola

Now we know if coefficient of is positive then opening of the parabola is upwards end opening is downwards is coefficient of  is negative.

Therefore, for the given graph option (A) y = is the answer.

for this pair of functions g(x)=x-2 and f(x)=|x| is (g o f)(a)= |a| -2

step-by-step explanation:

g(x)=x-2

f(x)=|x|

(g o f)(a)=?

(g o f)(x)=g(f(x))

(g o f)(x)=g(|x|)

(g o f)(x)=|x|-2

(g o f)(a)=|a|-2
