Answer:

<em>h(x) = -3(x + 1)^2 + 8</em>

Step-by-step explanation:

<em>h=-3x^2-6x+5  subtract 5 from both sides</em>

<em />

<em>h-5=-3x^2-6x  divide both sides by -3</em>

<em />

<em>(5-h)/3=x^2+2x  halve the linear coefficient, square it, add it to both sides....</em>

<em />

<em>(2/2)^2=1 add 1 to both sides...</em>

<em />

<em>(5-h+3)/3=x^2+2x+1, now the right side is a perfect square...</em>

<em />

<em>(8-h)/3=(x+1)^2  multiply both sides by 3</em>

<em />

<em>8-h=3(x+1)^2  divide both sides by -1</em>

<em />

<em>h-8=-3(x+1)^2  add 8 to both sides</em>

<em />

<em>h=-3(x+1)^2+8</em>

h(x)= -3(x+1)^2+8

Answer:

a) F

b) B, E, D

Step-by-step explanation:

a) The segment with the greatest gradient has the largest change in y-values per unit change in x-values

From the given option, the rate of change of the <em>y </em>to the<em> </em>x-values of B = the gradient = (4 units)/(2 units) = 2

The gradient of F = (-3units)/(1 unit) = -3

The gradient of A = 4/4 = 1

The gradient of C = -2/5

The gradient of D = 2/6 = 1/3

The gradient of E = 3/4

The segment with the greatest gradient is F

b) The steepest segment has the higher gradient

From their calculated we have;

The gradient of segment B = 2 therefore, B is steeper than E that has a gradient of 3/4, and E is steeper than D, as the gradient of D = 1/3

Therefore, we have;

B, E, D.

Can someone please find the vertex?
crimeas [40]
You have the correct axis of symmetry value. Nice work.

Plug that x value into the equation to get...
y = -2x^2 - 12x - 10
y = -2*(-3)^2 - 12*(-3) - 10 <<-- replace every x with -3; then use PEMDAS
y = -2*(9) - 12*(-3) - 10
y = -18 + 36 - 10
y = 18 - 10
y = 8

The vertex is the ordered pair (-3, 8)

Note: the axis of symmetry is the vertical line through the vertex
