Answer:
Yes. The interval (0, 5) is a reasonable solution because the function is positive in that region
Step-by-step explanation:
Hope it helps and I also hope yoh have a great rest of your day!
Remember the shortcut way for graphing quadratic equations
- A quadratic function has graph as parabola
- Hence on both sides of vertex the parabola is symmetric and axis of symmetry is vertex x values .
- y on both sides for -x and +x is same
#1
Vertex
As a is positive parabola facing upwards
Find y for same x distance from vertex
I took 3-1=2 and 3+1=4
- f(2)=2(2-3)²-1=2(-1)²-1=2-1=1
- f(4)=2(4-3)²-1=1
Now plot vertex and these two points (2,1) and (4,1) on graph then draw a parabola by freehand
#2
- y=(x-2)(x+4)
- y=x²+4x-2x-8
- y=x²+2x-8
Convert to vertex form
Vertex at (-1,-9)
Same take two equidistant x values
Let's take -1-1=-2 and -1+1 =0
- f(-2)=(-2+1)²-9=1-9=-8
- f(0)=(1)²-9=-8
Put (-1,-9),(-2,-8),(0,-8) on graph and draw a freehand parabola
#3.
Yes it can be verified by finding the coordinate theoretically on putting them on function then can be verified through putting them on graph whether they matches or not
The answer is a. $256
Step-by-step explanation:
The computation of the maximum allowable recurring debt is shown below:
Given ratio = 28:36
And the monthly income is $3,200
So the maximum expense on housing = 28% of $3,200 = $896
And, the maximum expense on total debt = 36% of $3,200 = $1,152
Now the maximum alloweable recurring debt is
= $1,152 - $896
= $256
3( x+ 3(4x-5))
3x + 9(4x-5)
3x + 36x - 45
39x - 45 is equivalent to 3( x+ 3(4x-5))
