A quadratic function is represented by the graph. (graph below.) (do a-d.)

(a) What is the equation of the axis of symmetry of the function?
(b) What are the coordinates of the vertex of the function?
(c) What are the coordinates of the x-intercepts of the function?
(d) What are the coordinates of the y-intercept of the function?

Answers

Answer:

The axis of symmetry is x=1

The vertex is (1,-9)

The x-intercepts are (4,0) and (-2,0)

The y-intercept is (0,-8)

Step-by-step explanation:

axis of symmetry is the line where the vertex is, so in the quadratic of x^2, the axis of symmetry would be zero because half of the equation is on one side and the other half on the other side

The vertex is the lowest point on the quadratic, on the y values

the x-intercepts are the places the graph intercepts the x-axis.

The y-intercepts are the places the graph intercepts the y-axis

Evaluate the following expression. log4 256
A. 64
B. 16 C. 4 D. 8

Answers

The correct answer is c.4

The simplified value of the expression  [tex]log_4[/tex] 256 is 4.

Thus, option (C) is correct.

To evaluate the expression [tex]log_4[/tex] 256, determine the power to which 4 must be raised to obtain 256.

So, the equation can be set up

[tex]4^x[/tex] = 256.

Now, put the value of x one by one as

[tex]4^2 = 16[/tex]

[tex]4^3 = 64[/tex]

[tex]4^4 = 256[/tex]

Thus, when the number 4 raise to the power 4 it gives 256.

Thus, option (C) is correct.
