if we zero out f(x), namely make y = 0, we can get the roots or x-intercepts for this quadratic equation
now, the equation is in x-terms, meaning is a vertically opening parabola, so the axis of symmetry will be x = something, a vertical line.
well, we have two x-intercepts, one at -4 and another at 2, and the vertex is right half-way between those guys
-4------------(-1)------------2
so the vertex is at x=-1, namely the axis of symmetry is x = -1.
Answer:
Step-by-step explanation:
Given
Required [Missing from the question]
G(T(x))
We have:
This implies that:
Substitute:
Open bracket
Answer:
Step-by-step explanation:
This shape is actually just a rectangle with a missing triangle. We can first find the area of the rectangle with and subtract the triangle.
Area of missing triangle = (b is the base and h is the height)
Base =
Height =
Area of missing triangle =
Area of the figure:
--------------------------------------------------------------------------
Alternatively, you can find the area of each individual shape and add them all up.
Area of the rectangle:
Area of square:
Area of triangle:
Total Area:
