4 0

Answer:

see below

Step-by-step explanation:

We can just add up all of these fractions:

2 1/8 + 7/8 = 2 8/8 = 3

8 5/8 + 4/8 = 8 9/8 = 9 1/8

3 + 9 1/8 = 12\frac{1}{8}

Consider the given function.
Misha Larkins [42]

Answer:

x -intercepts are x = -3 and x = 1

y-intercept at y = -3

The line of symmetry is x = -1

vertex is (h,k) = (-1,-4)


Step-by-step explanation:

Given a quadratic equations: h(x) = (x + 1)^2 - 4

The vertex for is :

h(x) = a(x - h)² + k 

where,'h' is the axis of symmetry and (h,k) is the vertex.

So from the given equation we will rewrite the equation as:

h(x) = (x - (-1))^2 - 4

Hence,h = -1 and k = -4

The line of symmetry is x = -1 and vertex is (h,k) = (-1,-4)

Now, we have to find the x intercepts,

using the equation,

(x + 1)² = 4

Taking the square root on both sides,

√(x + 1)² = √4

x + 1 = ± 2

x = 1 or x = -3

So x -intercepts are x = -3 and x = 1

For y-intercept put x = 0 into the real equation:

h(x) = (0 +1)^2 - 4

y = 1 - 4

y = -3

So y-intercept at y = -3

Here with I have attached the graph.

Thank you.
