using the given quadratic function f(x)=x^2+2x-15, find the following information"Equation of the axis of symmetry"

Sagot :

Answer:

x = -1

Explanation:

In a parabola with an equation equal to:

f(x) = ax² + bx + c

The equation of the axis of symmetry is x = -b/2a

So, if we have the equation:

f(x) = x² + 2x - 15

The value of a is 1, the value of b is 2, and the value of c is -15.

Therefore, the equation of the axis of symmetry is:

x = -2/(2*1) = -2/2 = -1

So, the answer is x = -1
