Answer:
vertex (5,2)
axis of symmetry: x=5
Step-by-step explanation:
vertex (h,k)
y = a(x - h)² + k
f(x)=(x-5)²+2 a = 1 h = 5 k = 2
vertex (5 , 2)
The axis of symmetry always passes through the vertex of the parabola. The x -coordinate of the vertex is the equation of the axis of symmetry of the parabola.
x = 5
Hi there! The answer is C.
Explanation:
We have the following equation:
To solve this type of equation (with an x in the denominator of a fraction) we must cross-multiply the numerator and the denominator.
Multiply
Divide both sides by 15.
