12. F(x) = 4x squared

y-intercept:

axis of symmetry:

vertex:

Step-by-step explanation:

To find the y-intercept, set x = 0 and solve for y.

I am assuming f(x) = y

The y-intercept of the equation is y = 0.

Now, for the axis of symmetry, you need the equation

In an equation..

In this case, there is only an a, so plug in the values into the equation.

The axis of symmetry is x = 0.

To find the vertex, change the format of the equation from standard form to vertex form.

Vertex form:

The vertex is

The vertex in this case is (0,0).

Graphing makes things a lot easier. If you can graph it, all you have to do is look at the graph and the answers are all there!

Hope this helped you!

answer: a. 13/44

step-by-step explanation: judging by the information given to us, we are looking for experimental probability. we can see that 13 males have chosen chocolate ice cream. there are 44 ice creams in total (remember that the total is always the denominator). so our answer is 13/44.

so, converting firstly the mixed fractions to improper fractions and then "adding".
