Question

f(x)=x^2 - x + 5/4
Graph by hand
I can't use my graphing calculator.

Answer 1

one approach
set up a table with the values of x and the corresponding values for f(x) then plot the points
another way
find the value of f(0) and the value when f(x) = 0 this will give you three points the minimum needed to get a sketch for a parabola

Answer 2

when x = 0 y = 5/4

when f(x) = 0 then x^2 - x + 5/4 = 0 solve for x


you have 3 points do the sketch
