Vocaloid:

that should be everything, let me know if you still have questions about it

zarkam21:

would I write it exactly how it is ,,, like for 8a I would write shift f(x) upward c units?

Vocaloid:

think about how the question is phrased, "explain the effect" so you would say something like "it shifts the graph up c units"

zarkam21:

perfect thanks

zarkam21:

so for b "shifts the graph to the left c units"

Vocaloid:

yes

zarkam21:

confused on c and d

Vocaloid:

"reflect f(x) in the x-axis" so turn this into a sentence that answers the question "the graph of -f(x) is the graph of f(x) reflected across the x-axis"

zarkam21:

and for d it would be the graph of f(x) is the graph of f(x) reflected across the x-axis

Vocaloid:

***y-axis ***f(-x)

Vocaloid:

the graph of f(-x) is the graph of f(x) reflected across the y-axis.

zarkam21:

8C "the graph of -f(x) is the graph of f(x) reflected across the y-axis" 8D "the graph of f(-x) is the graph of f(x) reflected across the y-axis."

Vocaloid:

first one should be x-axis not y.

zarkam21:

8C "the graph of -f(x) is the graph of f(x) reflected across the x-axis"

Vocaloid:

good

zarkam21:

okay and the same concept for 8e and 8f right?

Vocaloid:

yes

zarkam21:

he graph of y=f(x) is the graph of y=cf(x) reflected across the x-axis?

Vocaloid:

no|dw:1513274536502:dw|

Vocaloid:

multiplying the entire function by c is a vertical stretch/shrink by c and multiplying x by c is a horizontal stretch/shrink by c

Vocaloid:

|dw:1513274592308:dw|

zarkam21:

so for e it would be vertical and for f it would be horizontal

Vocaloid:

yes

zarkam21:

thank you =)
