There actually isn't anything to 'work'. There's no question there.
The function simply describes the relationship between two numbers.
It says that whatever you pick for the first number, the second number is
(-4 times the square of the first one) plus (7 times the first one) plus (6) .
Your teacher may have assigned you something to do with the function,
like draw the graph of it, or find its maximum value (2.9375), or find where
it crosses the x-axis (2.381 and -0.63) or the y-axis (6).
But we can't tell what you've been assigned to do with it. The function alone,
just as you've posted it, isn't asking a question, and doesn't call for any work.

Answer:
range of scores on final exam student get B is 90 to 100
Step-by-step explanation:
given data
Psychology 101 score = 66
average of his midterm = between 78 and 90
maximum = 100 points
to find out
range of scores on final exam student get B
solution
we consider here lowest marks need in final = x
so average at two marks should be
equation is
average marks = 0.5 × ( mid term marks + final marks ) .................1
put here value
78 = 0.5 × ( 66 + x )
x = 90
and
90 = 0.5 × ( 66 + x )
x = 114
so range 90 to 114
but maximum marks is 100 so
range of scores on final exam student get B is 90 to 100
