Answer:
7 units to the left of [tex]\sqrt{x}[/tex]
Step-by-step explanation:
Given f(x) then f(x + a) represents a horizontal translation of f(x)
• If a > 0 then a shift to the left of a units
• If a < 0 then a shift to the right of a units
Thus for [tex]\sqrt{x+7}[/tex] with a = 7 > 0
Then this represents a shift to the left of 7 units of [tex]\sqrt{x}[/tex]
