Question

in the function y=-3x^2+1, what effect does the negative sign have on the graph, as compared to the graph of y=x^2

Answer 1

see explanation

Explanation:

Given a quadratic function in standard form y = ax² + bx + c ( a ≠ 0)

• If a > 0 the the graph has a minimum value ∪

• If a < 0 then the graph has a maximum value ∩

Thus y = - 3x² + 1 ← has a maximum value and

y = x² ← has a minimum value
