Graph f(x)=x^2+1
Problem
Solution
Identify the type of function, which is a quadratic function in the form
ƒ(x)=a*x^2+b*x+c Determine the vertex of the parabola. Since
b=0 thex coordinate of the vertex isx=0 Calculate the
y coordinate of the vertex by evaluatingƒ(0)=0^2+1=1 The vertex is(0,1) Find the axis of symmetry, which is the vertical line passing through the vertex,
x=0 Select additional points to determine the shape. For
x=1 ƒ(1)=1^2+1=2 Forx=−1 ƒ*(−1)=(−1)^2+1=2 Plot the vertex
(0,1) and the points(1,2) and(−1,2) then draw a smooth upward-opening curve through them.
