A quadratic function is one of the form f(X)=ax^2+bx +c,where a,b and c are numbers with 'a' not equal to zero.
The graph of a quadratic function is a curve called a parabola. Parabola may open upward or downward and vary in 'width' or 'steepness' , but all have the basic "U" shape.
All parabolas are symmetric with respect to a line called the axis of symmetry. A parabola intersects its axis of symmetry at a point called the vertex of the parabola.
You know that the two points determine a line. This means that if you are given any two points in the plane,then there is one and only one line that contains both points.

Answer:
I guess it would be C, but i dont get "all numbers are answers" tho cos i thought this equation would be infinitely many solutionsssss
Step-by-step explanation:
4(x+1)+x=5(x-1)+9
4x + 4 + x = 5x -5 + 9
5x + 4 = 5x + 4
Hope this helpeddd
I think the value of y would be 9
because if you put 3 in place of x the equation would be
6.4(3)+2.8y then you would simplify it to 19.2+2.8y
19.2-44.4=25.5
25.2/2.8=9 which is the value of y
answer=9
The answer is 76 & 14, hope this helps.
