Question 131615: my book says to "write the equation of the axis of symmetry, and find the coordinates of the vertex of the graph of each function. identify the vertex as a maaximum or minimum. then graph the function" then it says
y=4x^2

my book says to "write the equation of the axis of symmetry, and find the coordinates of the vertex of the graph of each function. identify the vertex as a maaximum or minimum. then graph the function" then it says
y=4x^2
--------------
There are many ways to find the axis symmetry.
Your equation can be written as y = 4x^2+0x+0
a = 4, b= 0, c= 0
-----------
The axis of symmetry occurs where x = -b/2a = -0/8 = 0
The corresponding y-value is y = 4(0)^2 = 0
-------------------
So, the axis is x = 0 (this is the y-axis)
The vertex is (0,0)
The parabola opens upward because 4 is positive.
--------------------
what does it look like?
