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.

240=8(-5-7k) please help out and can y’all show how do it as well thank you
jok3333 [9.3K]

Answer:

k = - 5

Step-by-step explanation:

Given

240 = 8(- 5 - 7k) ← divide both sides by the multiplier 8

30 = - 5 - 7k ( add 5 to both sides )

35 = - 7k ( divide both sides by - 7 )

- 5 = k
