On a graph, x=0 at the y intercept.

Find the y-intercept of the equation

f(x)=x²+2x-24

• (0,2)

• (-24,0) (2,0)

• (4,0)

• (0,-24)

On a graph, x=0 at the y-intercept.

Find the y-intercept of the equation

f(x)=x²+5x-14

• (0,-14)

• (0,5)

• (0,-7)

• (0,2)

At the y-intercept, x=0.

Find the y-intercept of the function

y = -3(x + 2)² - 5

Select all that apply.

• $Domain:\ \ All\ Real\ Numbers$

• $Domain:\ \ y\le4$

• $Range:\ \ y\le4$

• $Range:\ \ y\ge4$

To find the vertex of the quadratic you need to first find the value for 'h' using the formula :
 $h=\frac{-b}{2a}$  
Use the equation:

 $f\left(x\right)=3x^2-12x+3$  

What is the value of h?

• h = 4

• h = -4

• h = 2

• h = -2

Which equation has a Maximum vertex?

Hint: Identify the a value first!

•  $y=-2x+4x^2-6$  

•  $y=3x^2+4x-8$  

•  $y=2-4x-6x^2$  

•  $y=.5x+1.4x^2-1000$  

The equation for the axis of symmetry line is

 $x=\frac{-b}{2a}$  

• true

• false
