Answer:
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,
