The function
is incresing and have positive values for all x. Then the function
is also increasing and have positive values for all x. This means that options B (values are negative) and D (function is decreasing) are incorrect.
At x=0,
.
In option A graph of the function passes through point (0,y), where y is near 3. In option C graph of the function passes through point (0,y), where y is near 1/5. So, you can conclude that the option C is correct.
X=7 All you need to do is combine like terms and then move the appropriate terms to the appropriate side.
