What is the rate of change for the numbers 3,5,7,9
JulsSmile [24]

Answer:

Plus 2 (+2)

Step-by-step explanation:

The rate of change is always a constant change from the given first term to the next one. In this case, you are adding 2 each time:

3 + 2 = 5

5 + 2 = 7

7 + 2 = 9

etc.

12. F(x) = 4x squared
Ymorist [56]

Answer:

y-intercept: y=0

axis of symmetry: x=0

vertex: (0,0)

Step-by-step explanation:

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

I am assuming f(x) = y

y=4x^2

y=4(0)^2

y=0

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

Now, for the axis of symmetry, you need the equation x=\frac{-b}{2a}

In an equation.. y=ax^2+bx+c

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

x=\frac{0}{2(4)}

x=0

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: y=a(x-h)^2+k

The vertex is (h,k)

y=4x^2 = 4(x+0)^2+0

(h,k)=(0,0)

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!
