Question 181670This question is from textbook Algebra 2
: a) find the y-int., the equation of the axis of symmetry, and the x-coordinate of the vertex
b)make a table of values that includes the vertex
c)use this information to graph the function
f(x)=x^2-x+5/4

:
:
vertex is (,)
:
axis of symmetry is x=1/2
:
y intercept is found by setting x to zero y=0^2-0+5/4=5/4
:
y intercept is (0,5/4)
:
for b) and c) just plug in values of x and solve for y for as many points as you want
:
we already know that for x=0 y=5/4(the y intercept
:
we also know that for x=1/2 y=1
:
try more such as x=2--->y(2)^2-2+5/4=13/4
try some negative values, x=-1--->y=(-1)^2-(-1)+5/4=13/4
:
interesting both the same value but this makes sense, since vertex is at x=1/2
x=2 and x=-1 are equal distances from 1/2
:
hope that helps
:
oh here is the graph:
no x intercepts on this parabola
