Explanation:

Answer 2

Option (D)

Explanation:

Parent function has been given as y = |x|

If the given absolute value function is scaled vertically or vertically stretched by a scale factor = k

where k ≥ 1

Then the dilated figure will be,

y = k|x|

Following the same rule,

for k =
`(7)/(2)`

Equation of the new graph will be,

y =
`(7)/(2)|x|`

Therefore, Option (D) will be the answer.
