Y=ax(0 square) -4x0 +3
=3
The intersection of this function and the Y axis is (0,3), and its coordinates have nothing to do with A.
No matter what the value of a is, this function passes through a fixed point (0,3) on the Y axis.
(2) There are two situations:
First, when a=0, the function is a linear function y=-4x+3, which is like a straight line with only one intersection with the X axis:
When y=0, -4x+3=0.
x=3/4
At this time, the intersection with the X axis is (3/4,0).
Second, when a≠0, the function is quadratic, and the discriminant △=0:
∴△=(b squared) -4ac=(-4) squared-12a =0.
16- 12a=0
∴a=4/3
Composition: a=0 or 4/3.
I am glad to solve the above problems for you, and I hope it will help your study! ≤、≥ ∠
