Determine the coordinates of the vertex for each quadratic function and whether the parabola has a maximum or minimum. 4. y = x²

GREYUIT [131]

Answer:

minimum, coordinates of vertex: (-3,-11)

explanation:

$\sf y =x^2 +6x-2$

x coordinates on vertex:

<u>solving steps</u>:

$\sf \dfrac{-b}{2a}$

$\sf \dfrac{-6}{2(1)}$

$\sf -3$

<u>Find y-coordinate on vertex:</u>

$\sf y =x^2 +6x-2$

$\sf y =(-3)^2 +6(-3)-2$

$\sf y =-11$

$\mathrm{If}\:a < 0,\:\mathrm{then\:the\:vertex\:is\:a\:maximum\:value}$

$\mathrm{If}\:a > 0,\:\mathrm{then\:the\:vertex\:is\:a\:minimum\:value}$

coordinates: (-3,-11) thus minimum

Trina's car uses 12 gallons of gas to travel 144 miles. If she has 6 gallons of gas in the tank, how much more gas will she need

PSYCHO15rus [73]

Answer: 14gallons

Step-by-step explanation:

12gallons/144miles = 1gallon/12miles

Therefore 6gallons = 12*6 = 72miles.

In order to cover 240miles, she will need 240/12 = 20gallons.

20-6 = 14gallons

She will need 14gallons of gas more.

If g(x) = -2x+7, what is the new function defined by h(x) = g(2x^2 +1)

hammer [34]

Answer:

h(x) = - 4x² + 5

Step-by-step explanation:

To find h(x) = g(2x² + 1), substitute x = 2x² + 1 into g(x)

h(x) = - 2(2x² + 1) + 7

= - 4x² - 2 + 7

= - 4x² + 5
