Applying and analysing functions

What is the zero of the following graph?

• -6

• 6

The x-intercepts of the graph of a function.

The points for which f(x)=0

• Output

• Zeros

• X-axis

• Origins

What is the X-Intercept?

• x= 0

• x= 4

• x= 5

• x= -5

Where is a zero (x-intercept) found on a graph?

• Where the function crosses the y-axis.

• Where the function crosses the x-axis.

• On the top of the graph always.

• Not enough information to answer.

^{What is the zero of the function?}

• x = 1

• x = 2

• x = -1

• x = -2

What is the zero of the function based on the graph?

• f(0) = 0

• f(6) = 0

• f(8) = 0

• This graph doesn't have a zero.

Which function(s) below do NOT have a y-intercept? Check all that apply.

• $y=\frac{x^2+4x-5}{x^2+2x}$

• $g\left(x\right)=\frac{x^2-5x}{x^3-4x^2-x+4}$

• $f\left(x\right)=\frac{x^3-9x^2}{2x^3-7x^2+5x}$

• $h\left(x\right)=\frac{3x+6}{x^2-5x+6}$

What is the y-intercept of

 $f\left(x\right)=\frac{x^2-3x}{x+3}?$  

• y = 3

• y = 1

• y = 0

• y = -2
