Which graph is the correct one?

Mathematics
1 answer:
cestrela7 [59]3 years ago
3 0

Answer:

The upper graph

Step-by-step explanation:

We have two quadratic function here

y=-x^{2} +3x+5\\y=x^{2} +2x\\

If we perform the function f(x) + g(x), which is nothing more than the sum of the two functions, we obtain a linear function, since the quadratic terms are eliminated by themselves

5x+5

Which of the following will generate a graph that is 3 units to the left of y = x3?
Mamont248 [21]

Answer:

(3) y=(x+3)

Step-by-step explanation:

I'm not sure what is the parent function, but in most graphs if you will shift it to the left or right (negative sign or positive sign, respectively), it will be inside a parenthesis and the opposite sign is the real movement.

For a cubic function these will be the movements:

f(x)=(x+/-h)^3+/-k

Only the opposite sign of h will be the real movement, while k's sign will automatically indicate the correct movement.

h= x-axis movement (horizontal, inside of the parenthesis in the equation)

k= y-axis movement (vertical, outside of the parenthesis in the equation)

Hope it helps

What is the area of the shaded region?
Verdich [7]
<h2>Area of Composite Shapes</h2>

To find the area of composite shapes, we can break the bigger shape down into small, simpler shapes, and find the sum of their areas.

For this triangle, we will need to know the formula to find the area of a triangle:

A=\dfrac{1}{2}bh

<h2>Solving the Question</h2>

The given shape can be seen as one large triangle with a little triangle cut out of it. To find the shaded region, we can:

  1. Find the area of the large triangle
  2. Find the area of the little triangle
  3. Subtract the area of the little triangle from the large triangle

<h3>Area of the Large Triangle</h3>

A=\dfrac{1}{2}bh

⇒ Plug in the values given for the base and height:

A=\dfrac{1}{2}(5)(2+4+6)\\\\A=\dfrac{1}{2}(5)(12)\\\\A=(5)(6)\\\\A=30 mm^2

<h3>Area of the Small Triangle</h3>

A=\dfrac{1}{2}bh

⇒ Plug in the values given for the base and height:

A=\dfrac{1}{2}(3)(4)\\\\A=(3)(2)\\\\A=6mm^2

<h3>Subtract the Area of the Small Triangle from the Area of the Large Triangle</h3>

30 mm^2-6mm^2\\=24mm^2

<h2>Answer</h2>

The area of the shaded region is 24mm^2.
