Question

find the x and y intercepts:

f(x)=-x^2 +3x+10

Answer 1

for the y intercept let x = 0

for the x intercept, let y=0 or f(x) = 0
that is ...
solve x^2 + 3x + 10 = 0
Hint: there is no real solution, so there are not x intercepts

explanation:
You are looking at a parabola which opens upwards and whose vertex is above the x-axis, so how can the graph cut the x - axis ?

Thanks, I kept coming up with strange answers. That makes sense.
