What is the axis of symmetry for the graph of y – 4x = 7 – x2 ? x = 2 y = 2 x = 11 y = 11

option 1st is correct

x = 2

Step-by-step explanation:

For a quadratic equation:

.....[1], the axis of symmetry is given by:

Given the equation:

Add 4x to both sides we have;

We can write this as:

On Comparing with [1] we have;

a = -1 , b = 4 and c = 7

then;

therefore, the axis of symmetry of the given equation:

is, x = 2
