What is the vertex of the graph of the function f(x) = x2 + 8x - 2?
vlabodo [156]

Answer:

Vertex is (-4, -18)

Step-by-step explanation:

f(x) = ax^{2} +bx +c

Let (h, k) be the vertex

An easy way to find h is to use the formula h = -b/2a

In your case where f(x) = x^{2} +8x - 2   a = 2 and b = 8

So, h =  -8/2(1) = -8/2 = -4

Substitue -4 in for x to find k

k = (-4^{2}) + 8(-4) - 2

  = (16) - 32 - 2

  = 16 - 32 - 2

  = -18

Vertex is (-4, -18)

Note:  Another way to find the vertex is to complete the square, but this can really be difficult in some cases

Helen [10]
<h3>Answer:   426 square feet</h3>

Work Shown:

A = area of the rectangle

A = length*width

A = 26*15

A = 390 square feet

B = area of the triangle

B = base*height/2

B = 8*9/2

B = 72/2

B = 36 square feet

C = total area

C = A+B

C = 390+36

C = 426 square feet
