Answer:
Step-by-step explanation:
You have shared only one graph, that of a quadratic function with vertex at (0, 0) and an equation based upon y = ax^2, where a is a constant coefficient.
Please go back to the source of your question and describe the other graphs that were given to you.
The graph that shows a straight line is the linear function.
Answer:
The factor form is:

Step-by-step explanation:
Here we have to find the factor of the expression:

So we need to take out the common terms, as we do for finding the greatest common factors.
Now the expression that is given can be re-written as:

Next, we will find the common terms, as follows;

Now we will factorise the expression:

as follows;

So the final factor form is:

Answer:
4/2 45/63
Step-by-step explanation:
Answer:
3.5 cm
Step-by-step explanation:
2.5 is half of 5 so you divide 7 by 2 and you get 3.5
