The graph of which function has an axis of symmetry at x = 3? f(x) = x2 3x 1 or f(x) = x2 – 3x – 3 or f(x) = x2 6x 3 or f(x) = x2 – 6x – 1

Option 4th is correct

Step-by-step explanation:

A quadratic equation is in the form of: .....[1]; then the axis of symmetry is given by:

As per the statement:

To find :

The graph of which function has an axis of symmetry at x = 3

From the given options:

Option 4th is the graph of a function which has axis of symmetry at x = 3

Consider a function:

On comparing with [1] we have;

a = 1  and b = -6

then;

⇒

Therefore, The graph of which function has an axis of symmetry at x = 3 is,

the 2 figures are congruent bc if you reflect abcd over the y axis then over the d axis the figures overlap
