Applying and analysing functions

What is the zero of the linear function graphed below ?

• 5

• 1

• -1

• -5

What is the zero (x-intercept)?

• x= 0

• x= 4

• x= 5

• x= -5

How do you find the x-intercept(s) for a rational function?

• Set the function = 0 and solve.

• Evaluate f(0)

• Set the denominator = 0 and solve.

• Set the numerator = 0 and solve.

• Factor the function.

Is there a x-intercept?

• yes

• no

Which function has an x-intercept at (2, 0)

• $h\left(x\right)=\frac{1}{x}$

• $t\left(x\right)=\left(x-2\right)\left(x-3\right)$

• $q\left(x\right)=\frac{1}{x-2}$

What is the x-intercept?

• None
• (5, 0)
• (-5, 0)
• (0, 5/4)

• (5,0), (-5,0)

• (3,0), (-3,0)

• None

• (0,0)

Identify the y-intercepts. 
 $y=\frac{x^2-1}{2x^2+8x+6}$  

•  $\left(1,\ 0\right)$   and  $\left(-1,\ 0\right)$  

•  $\left(0,\ 1\right)$   and  $\left(0,\ -1\right)$  

•  $\left(0,\ -\frac{1}{6}\right)$  

•  $\left(\frac{1}{6},\ 0\right)$
