What is the equation of the axis of symmetry for the graph of #f(x) = 2x^2 + x - 3#?

Answer 1

Nathan Axel

The equation given to us is in the Standard form #y = ax^2 + bx + c# where #a = 2, b = 1 and c = -3#

The Axis of Symmetry is given by the formula #x = -1/(2*2)#

# x = -1/4#

#color (green)( x = -1/4# is the Axis of Symmetry of the Parabola with the equation #y=2x^2+x-3#

The equation of the axis of symmetry for the graph of ( f(x) = 2x^2 + x - 3 ) is ( x = -\frac{b}{2a} ), where ( a = 2 ) and ( b = 1 ). So, ( x = -\frac{1}{2(2)} = -\frac{1}{4} ).

When evaluating a one-sided limit, you need to be careful when a quantity is approaching zero since its sign is different depending on which way it is approaching zero from. Let us look at some examples.
