Question

f(x)=1/4 x^2

Answer 1

what's the question?

Answer 2

If this is connected to your last question about if it had any roots, then yes, it does. In this context roots just mean when is this thing zero (aka intersects x-axis). So,

0 = (1/4)x²
Times 4.
0 = x²
Squareroot.
x = 0

Since we only got one answer, it only intersects the x-axis once.

Answer 3

@saifoo.khan it says find the label the vertex and line of symmetry

Answer 4

vertex = (0,0)
line of sym, x = 0

Answer 5

I agree with saifoo.khan's answer. If this graph had more than one x-intercept, then in order to find the vertex, you would average the x values. This is because a graph of degree 2 (biggest exponent is 2) is symmetrical so the x value of the vertex will always be right between the roots.

Answer 6

Solve the formula for the given variable A=3s^2, for s

Answer 7

\[\sqrt {\frac A 3}\]

Answer 8

Answer 9

3,7

Answer 10

find the vertex and line of symmetry f(x)=-x^2+10x+3
