If the range of the function y = f(x) is {y | y ≥ 11, y ∈ R}, then the range of the new function g(x) = f(x + 2) - 3 is
1 answer:
Answer:
y ≥ 8
Explanation:
Note that if f(x) is transformed into f(x + a) - b
The original functions is shifted a units to the left and b units downward.
Horizontal shifting will not affect the range of the function, only vertical shifting will change its range.
From the given, g(x) is the transformation of f(x) with
f(x) is shifted 2 units to the left and 3 units downward, we will disregard the horizontal shifting.
Since f(x) has a range of y ≥ 11, and g(x) is 3 units downward, the range will also move 3 units downward.
y ≥ 11 - 3
The answer is y ≥ 8

First of all, we need all logarithms to have the same base. So, we use the formula
To change the second term as follows:
Finally, using the property
we have
So, the equation becomes
We can now use the formula
to write the equation as
Now consider both sides as exponents of 2:
This equation has no "nice" solution, so I guess the problem is as simplifies as it can be
