Answer:

2(x+1)²-3

Step-by-step explanation:

Using the vertex formula we can write the follwoing equation

y=a(x+1)²-3

We need to solve for a

we know that when x= 2 y = 15

So we can write

15=a(2+1)²-3

15=9a-3

18=9a

a=2

Which means our final equation is

2(x+1)²-3

in standard form (just in case)

2x²+4x-1

Naddika [18.5K]

Answer: $5

Step-by-step explanation: This can be represented by the equation

40 + 12T = 25 + 15T

We just solve for T.

Subtract 12T from both sides

40 = 25 + 3T Subtract 25

15 = 3T Divide by 3

5 = T

(b)The graph of y = g(x) is shown. Draw the graph of g(2x). Will award 100 Brainly points
ivanzaharov [21]

Using the stated transformation, the graph of g(2x) is given at the end of the answer.

<h3>Horizontal stretch and compression</h3>

An horizontal stretch or an horizontal compression happens when a constant is multiplied at the domain of the function, as follows:

g(x) = f(ax).

The definition of stretch or compression depends on the value of the constant a, as follows:

  • If a > 1, it is a compression by a factor of 1/a.
  • If a < 1, it is a stretch by a factor of 1/a.

In this problem, the rule is:

f(x) = g(2x).

Meaning that f(x) is an horizontal compression by a factor of 1/2 of g(x), and then the vertices are given as follows:

  • (0,0).
  • (1,-4).
  • (2,-2).

That is, in each vertex, the x-coordinate was divided by 2, and thus the graph with these vertices is given at the end of the answer.

Answer:

some statements that are true are :

Step-by-step explanation:

it has only 1 line of reflectional symmetry.

a line of symmetry will connect 2 vertices.

a line of symmetry will connect a vertex and a midpoint of an opposite side.

it has 7 fold symmetry.

a line of symmetry will connect the midpoints of 2 opposite sides.
