Mark the vertex and graph the axis of symmetry of the function.<br><br>f(x) = (x – 2)2 – 25

Y_Kistochka [10]

Answer:

Vertex (2 , -25)

Axis of symmetry: x = 2

Step-by-step explanation:

<h3>Vertex of parabola:</h3>

The vertex is the highest point if the parabola open downwards and the lowest point if the parabola opens upward.

f(x) = (x - 2)² - 25

The given quadratic function is in vertex form.

f(x) = a(x - h)² + k

Here, (h , k) is the vertex of the parabola.

h = 2 ; k = -25

$\sf \boxed{\bf Vertex (2 , -25)}$

<h3>Axis of symmetry:</h3>

The axis of symmetry is the vertical line that divides the parabola into two equal halves and it passes through the vertex of the parabola.

Axis of symmetry: x = h

$\sf \boxed{\bf x = 2}$

guapka [62]

Answer: $108.60

Step-by-step explanation:

Initial cost: $95.50

Tip is an additional cost. They want to give a tip of 20%, so they will give additional 20% of the initial cost.

$90.50 + (90.50 * 0.2)

= $90.50 + $18.10

= $108.60
