f(x):

g(x)

Step-by-step explanation:
When a function is of the form:

The equation of the axis of symmetry is

The given function is

We can see that h=-4
Hence the equation of axis of symmetry is

From the graph, the axis of symmetry of h(x) is the vertical line that divides the parabola into two congruent halves.
This line is

Answer:
Im pretty sure the 3rd choice on #2 is an irrational number...
Step-by-step explanation:
The cost is £79.76. Since the car covers 560 miles and 34.5 miles is travelled by one gallon. So, dividing 560 by 34.5 we get 16.23. Since 1 gallon is 4.55 litres, 16.23 gallons is 73.8465. Now the cost of petrol is £1.08 per litre. So, multiplying 73.8465 by £1.08 we have £79.76
