Let f(x) = −x2 + 5x − 7.
Find and simplify the difference quotient,
f(x + h) − f(x)
h
.

i would say c is the best answer, hope it's right!

good luck! =)

“ a line segment that has the endpoints on the circle and passes through the midpoint is called the diameter. the diameter is twice the size of the radius. a line segment that has its endpoints on the circular border but does not pass through the midpoint is called a chord. a circle is the same as 360 small circle up the number 0 . i hope this .
