Which type of dilation?

 $f\left(x\right)=\left(Bx\right)$  

• Horizontal

• Vertical

How do I find the y-intercept of a function with an equation? (Two are correct)

• Find where the graph crosses the x-axis

• Put 0 into my function for x and calculate

• Start with a y-intercept I know and use transformations

• Put 0 into my function for y and calculate

 $3^x$  

Here is a parent function. What is the y-intercept?

• (0,0)

• (0,1)

• (1,0)
