As for the domain, the only restriction comes from the logarithm. The argument of a logarith must be strictly positive, so we have
As for the range, we have:
- The range of
are all real numbers
- If we change to
we're translating the function horizontally, so the range remains the same
- If we change to
we're stretching the function horizontally, so the range doesn't change
- If we change to
we're translating the function 1 unit up, but the range is already all the real numbers, so it doesn't change.
a) (2a - b)² = (4a² - 4ab + b²)
b) (10m - n²)² = (100m² - 20mn² + n⁴)
c) (4x - 4²) = (16x² - 8x + 4⁴)
d)
e)
f)
The rate of change is $55 per hour. The means that the hourly rate of the designer is $55 per hour
<h3>Linear equation</h3>A linear equation is in the form:
y = mx + b
where y, x are variables, m is the slope of the line and m is the y intercept.
Let y represent the total cost of hiring for x hours. Hence:
- Using the points (0, 125) and (15, 950)
The rate of change is $55 per hour. The means that the hourly rate of the designer is $55 per hour
