We first need to write the function in standard form.
y = -x^2 - 7x + 18
To find the axis of symmetry, we do -b/2a
The a and b are the coefficients of the x values.
So a would be -1 since -x is same as -1x
Follow that, b would be -7.
Then just plug the values in. - (-7)/2(-1) = -7/2
The axis of symmetry is -7/2
The remove_sort_reverse function takes a list, removes all "s" in the list elements, sorts and then reverses the remaining elements
<h3>The actual program</h3>
The program in Python, where comments are used to explain each line is as follows:
#This defines the function
def remove_sort_reverse(myList):
#This iterates through the list
for i in range(len(myList)):
#This removes all the s in the list elements
myList[i] = myList[i].replace("s","")
#This sorts and reverses the list elements
myList.sort(reverse=True)
#This returns the updated list
return(myList)
