Question

Sketch the graph: f(x) = 5x^2 + 1
How do you solve to be able to sketch it?

Answer 1

@LeightnerRach y = 5x^2 + 1

Answer 2

for any value of x y >0
when x = 0 y = 1

Answer 3

well the curve is a parabola that is always positive and has a y-intercept of y = 1

the line of symmetry is the y-axis

so a sketch is simply



you could use a table of values

x = -3, -2, -1, 0, 1, 2, 3,

subsitute them plot the ordered pairs and then draw a line though them
