Because there is no solution if any number divide by 0
Answer:
A turning point is the highest or lowest point on a quadratic graph.
Step-by-step explanation:
A quadratic graph looks something like the graph below.
The equation of a quadratic graph would normally look like
+/- ax^2 + bx + c
An example might be -16x^2 + 5x + 4
Note the negative symbol in front of the 16. The negative means that the graph will be facing downwards, or that the turning point is the highest point. A positive graph will mean that the graph is facing upwards, or that the turning point is the lowest point.
Essentially, it is the location where a graph has its lowest or highest point and where the y-values (can include x-values in horizontal quadratics) "turn" to the direction they originated.
Step-by-step explanation:
12a = 2×2×3×a
16 c^2 = 2×2×2×2×c×c
hence h.c.f = 2×2
= 4
The graph does not represent a function. When x=2, there are two different outputs, meaning it cannot be a function.
