Which function represents a translation of the parent cubic function 8 units to the left? h(x) = x3 + 8 h(x) = x3 – 8 h(x) = (x
Ksju [112]

Using the definition of the Vertical shifts of graphs of the function :

"Suppose c>0,

To graph y=f(x)+c, shift the graph of y=f(x) upward c units.

To graph y=f(x)-c, shift the graph of y=f(x) downward c units"

Again we recall the definition of Horizontal shifts of graphs:

" suppose c>0,

the graph y=f(x-c), shift the graph of y=f(x) to the right by c units

the graph y=f(x+c), shift the graph of y=f(x) to the left by c units. "

consider f(x)=x^3 is the parent function.

h(x)=x^3+8 shifts the graph f(x)=x^3 upward by 8 units

h(x)=x^3-8 shifts the graph f(x)=x^3downward by 8 units

h(x)=(x+8)^3 shifts the graph f(x)=x^3 left by 8 units

h(x)=(x-8)^3 shifts the graph f(x)=x^3 right by 8 units.
