1. suppose you are saving money for a new cell phone. at week 0 you have $20 and at week 10 you have $100. if y represents the amount of money you have saved and x represents the number of weeks, find and interpret the slope of the linear equation.
1. 1/8; $8 is put away each
week.
2. 10; $10 is put away each week.
3. 8; $8 is put away each week.
4. 1/10; $10 is put away each week.
2. if a function f (x) is shifted to the left one unit, what function represent the transformation?
1.f (x+1)
2. f (x- 1)
3. f (x)+1
4. f (x)- 1
3. let g (x) be the reflection of f (x)=x^2+5 in the x- axis. what is the function rule for g(x)?
1. g (x)=- x^2- 5
2. g (x)=x^2+5
3. g (x)=x^2- 5
4. g (x)=- x^2+5
4. what transformations change the graph f (x) to the graph g (x)? f (x)=- 7x^2 g (x)=-35x^2+5
1. the graph stretched vertically by a factor of 1/5 and slanted down 5 units
2. the graph stretched vertically by a factor of 5 and translated down 5 units.
3. the graph stretched vertically by a factor of 1/5 and translanted up 5 units.
4. the graph stretched vertically by a factor of 5 and translated up 5 units.
8. write an equation for the following transformation of y=x a vertical stretch by a factor of 6.
1.y=6x
2. y=x/6
3. y=x+6
4. y=x-6
9. what transformations change the graph of f (x) to the graph of g (x).
1. the graph of g is the graph of f translated to the right 3 units and up 7 units.
2. the graph of g is the graph of f translated to the left 3 units and down 7 units.
3. the graph of g is the graph of f translated up 3 units and to the left 7 units.
4. the graph of g is the graph of f translated down three units and the right 7 units.
