Suppose the function h(x)=2x-9 is translated up 5 united to become a new function, i(x). what the equation of the new function?
a. i(x)=7x-4
b .i(x)=2x-4
c. i(x)=7x-9
d. i(x)-2x-14

Respuesta :

Option B

i(x) = 2x - 4 is the equation of the new function

Solution:

Given that the function h(x) = 2x-9 is translated up 5 united to become a new function, i(x)

To find: Equation of new function

The graph of a function can be moved up, down, left, or right by adding to or subtracting from the output or the input.

Adding to the output of a function moves the graph up

Therefore,

Given function is:

h(x) = 2x - 9

Translated up by 5 units

Therefore, new function is:

i(x) = h(x) + 5

i(x) = 2x - 9 + 5

i(x) = 2x - 4

Thus Option B is correct
