Answer:
A
Step-by-step explanation:
Given f(x) then f(x + a) is a horizontal translation of f(x)
• If a > 0 then a shift left of a units
• If a < 0 then a shift right of a units
Here f(x) is shifted 3 units left , then
f(x) → f(x + 3)
Given f(x) then f(x) + c is a vertical translation of f(x)
• If c > 0 then a shift up of c units
• If c < 0 then a shift down of c units
Here f(x) is shifted 4 units down , then
f(x) → f(x) - 4
Thus
f(x) = → f(x) =
- 4
Answer:
Option A.
Step-by-step explanation:
The given expression is
We need to find the difference round to the less precise measurement.
Taking out the common factor.
Precise measurement of given expression is 81.2g.
A measurement with more decimal places is more precise and vice versa.
Now, approx the answer to the the nearest whole measure.
The less precise measurement of given expression is 81g.
Therefore, the correct option is A.
