Equation :
This parabola is facing downwards and highest point of the parabola is it's vertex.
Highest point is (-2,2)
so the vertex is (-2,2)
The graph is passing through (-1,0)
Equation in vertex form is


Substitute back in Equation

the graph has two x intercepts -1 and -3
that means (x+1) and (x+3) are the factors
multiply factors to get the equation in standard form

-2x^2-8x-6=0
Answer:
f(x) = (X^3 +6) + 4
Step-by-step explanation:
to move left add +6 from <u>inside</u> the parenthesis
to move up add +4 <u>outside</u> of parenthesis
<em>*since there were no parenthesis you add them*</em>
Answer:
Dependant variables- how much fertiliser depends on the size of the lawn
Independent variables- Gardeners will always buy fertiliser.
Step-by-step explanation:
True.
Let's say that you have two pieces of paper that both represent planes. If you cross them, you'll be able to see that the intersection of these two pieces of paper is a line.
Answer: f(30) = -1
You would substitute every X with 30
