Let's compare the given function with the model for a quadratic equation:
Since the value of a is positive, the parabola has its concavity upwards, and the function has a minimum value.
The minimum value can be found calculating the y-coordinate of the vertex:
Therefore the minimum value is -24.
10x:8x=270
18x=270
x=15
Now
150:120
Answer:
None,
a=1/2
Step-by-step explanation:
Lets group together 'a' terms in one side of equations and lone terms on the other.
To do this, simply sum 'a' to both sides of equation, and also, subtract -1 (lone term).
3a+a=3-1
this leads to
4a=2
Where we obtain a=1/2
Answer:
False
Step-by-step explanation:
This is not a function
The same x value goes to 2 different y values
5 goes to both 2 and 1
This is not a 1 to 1 correspondence
