(fg)(x)=f(g(x))
So all you have to do is plug the g(x) in
3(3x^2)+9=f(x)
9x^2+9=f(x)
Π=3.14159265359 so I guess 1, is the answer
Answer:
The answer is option A.
∆BDC is a right angled triangle
Angles in a triangle add up to 180°
That's
z + 35 + 90 = 180°
z = 180 - 35 - 90
z = 55°
Alternate angles are equal
Angle DBC = Angle BDA
That's
35 = 7y
Divide both sides by 7
y = 5
y = 5 z = 55
