Instructions: Given the vertex, fill in the vertex form of the quadratic function..
miskamm [114]

Answer:

\implies y=(x-2)^2-6

Step-by-step explanation:

<u>Vertex form of a quadratic equation</u>:

y=a(x-h)^2+k

where:

  • (h, k) is the vertex
  • a is some constant

<u>Given vertex</u>:  (2, -6)

⇒ h = 2 and k = -6

Substitute the values of h and k into the formula:

\implies y=a(x-2)^2+(-6)

\implies y=a(x-2)^2-6

As we have not been given a value for the constant a, assume this is 1.

Therefore, the <u>vertex form</u> of the <u>quadratic function</u> with vertex (2, -6) is:

y=(x-2)^2-6

Crank

Answer:

the answer is c: s=40(1.1)^m, s=20(1.15)^m

Step-by-step explanation:

in option A, (0.10) and (0.15) make it exponential decay rather than exponential growth like it's supposed to be.

In option B, the rate of growth is supposed to be on the exponent, not the sales themselves in the equation

option c is correct I just finished the test
