Answer:

Answer:

x = 2

Step-by-step explanation:

The vertex form of the parabola is given by  

Comparing this equation with vertex form of a parabola , where (h,k) is the vertex

h = 2

k = 3

Hence, vertex is (2,3)

Now, axis of symmetry of a parabola passes through the vertex and divide the parabola in two equal halves.

Hence, axis of symmetry of the parabola is given by

x = h

x = 2

Third option is correct.

Find the cube of 20 <br><br> A. 40<br> B. 400<br> C. 800<br> D. 8000
lapo4ka [179]
The cube of 20 can be written as 20^{3}. Split the 20 up into 2*10. Even though we are doing the cube of this value, first do 2*3=8 and then do 10^3=1000. Now multiply these numbers together so it is 8*1000=8000. Which is answer choice D. 8000
