Answer:
x = 14
BE = 6
Step-by-step explanation:
to find 'x': BG = 1/2[(x-9) + (3x-13)]
BG = 4x-22 / 2
BG = 3x-25
3x-25 / 1 = 4x-22 / 2
cross-multiply:
4x-22 = 2(3x-25)
4x-22 = 6x-50
-2x = -28
x = 14
to find 'BE': CB = BE
2x+4 = 7x-1
-5x = -5
x = 1
BE = 7(1) - 1
BE = 6
The vertex of the function is (–3, –13).
The axis of symmetry for the function is x = 3.
The graph increases over the interval (–3, infinity symbol).
The function does not cross the x-axis.
Find the vertex of the parabola given by the formula :
1. As you can see this vertex form differ from the vertex form in option A, then A is incorrect.
2. When x=-3, f(-3)=-13 and the vertex has coordinates (-3,-13) - option B is true.
3. From the attached graph you can see that the axe of symmetry is line x=-3 that passes through the vertex. This means that choice C is incorrect.
4. From the attached graph you can see that the function is increasing for x>-3 and decreasing for x<-3. Option D is correct.
5. The graph intersects x-axis at two points (see attached diagram). Option E is incorrect.
It is clear from the information given that Both Options B and Option D are correct. While options A and C are incorrect.
The set of all points in the plane of the form (x, f(x)) is known as the graph of a function f(x).
In order words, it is the collection of all ordered pairs of the function. Examples of real-life applications of GraphFunctions are:
