Question

The given function has 2 real roots.
f(x) = x2 – 8x + 25
Select one:
True
False

Answer 1

Can I get the answer from someone please?

Answer 2

real roots, are the x axis intercepts, when y=0

notice this parabola opens upwards and the vertex min value is when x=0, y=25

so it starts at 25 and opens up, wont ever cross the x axis

Answer 3

or try solving that for f(x) = 0 and you don't see real numbers
