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!

3=-m+b -2=2m+b<br> find m and b
kiruha [24]

Answer:

b = 4/3

m = -5/3

Step-by-step explanation:

3=-m+b

-2=2m+b

Subtract the second equation from the first

3=-m+b

-( -2=2m+b)

------------------------

  3=-m+b

+ 2=-2m-b

------------------------

5= -3m +0b

Divide by -3

5/-3 = -3m/-3

-5/3 = m

Now we can find b

3=-m+b

3 = - (-5/3) +b

3 = 5/3 +b

Subtract 5/3 from each side

3 -5/3 = b

9/3 - 5/3 = b

4/3 =b
