Answer:

$for \: \: dmain \: of \: {f}^{ - } \: \: is \: equal \: f \: range \\ y = \sqrt{x } - 5 \\y \: range \: is \: y \geqslant - 5\\ y + 5 = \sqrt{x} \\ x = {(y + 5)}^{2} \\ {f}^{ - 1} = {(x + 5)}^{2} \\ \\ dmain \: of \: \: {f}^{ - 1} \: x \geqslant - 5$

Consider the function f(x)=-3x2+12x-5. What is the location of the vertex? Write your answer as an ordered pair.

natita [175]

Answer:

The (x,y) point of the vertex is usually labelled as:

Vertex = (h, k)

h = -b / 2a

k = ah^2 + bh + c

f(x) = -3x^2 + 12x -5

a = -3 b=12 c=-5

h = -12 / -6 therefore h = 2

k = -3*2^2 + 12*2 -5

k = -12 + 24 -5 therefore k = 7

Vertex (2, 7)

Answer:

Step-by-step explanation:

4(2x+3)-3(x+4)

4(2x) + 4(3) - 3(x) - 3(4)

8x + 12 - 3x - 12

8x - 3x + 12 - 12

Explanation

To determine if two segments are the same length,we can use a. compass. .
First,you have to place the compass point at. A A A. and.
On the other side,if that does not happen,if arc do not interesect the point. D D D. ,we can conclude that the given segments are not the same length.
