The quadratic function y = - 3x draws an image
The image of quadratic function y = 3x ^ 2 is
After (0,0) (1,3) (2,12) (- 1,3) (- 2,12) On Y-axis symmetry
What is the specific answer?
I've been learning for a long time. I don't know what to answer
Finding the intersection of quadratic function y = 3x ^ 2-5x + 1 and X axis
It intersects with the X axis, so we only need to let y = 0 and solve the quadratic equation about X
Why is the analytic expression of quadratic function y = ax ^ 2 + BX + C, if y = ax ^ 2-bx-c or other
Because a, B and C are all natural numbers, including negative numbers
Using a plus sign is mainly due to the habit of calculation
