Graph f(x)= -(x-2)²+4<img src="https://tex.z-dn.net/?f=" id="TexFormula1" title="" alt="" align="absmiddle" class="latex-formula
Mandarinka [93]

Answer: See the graph attached.

Step-by-step explanation:

The standard form of a quadratic function is:

f(x)=a(x-h)+k

Where (h,k) is the vertex of the parabola.

If a is negative, then the parabola opens down.

Then, for the function:

f(x)=-(x-2)^2+4

You can identify:

h=2\\k=4

Then the  vertex of the parabola is at (2,4)

Note that a=-1, therefore the parabola opens down.

Find the intersection with the x-axis. Substitute f(x)=0 and solve for x:

0=-(x-2)^2+4\\0=x^2-4x\\0=x(x-4)\\\\x_1=0\\x_2=4

Knowing that the vertex is at (2,4), the parabola opens down and it intersects the x-axis at x=0 and x=4, you can graph the function, as you observe in the figure attached.

Which inequality shows twelve times the sum of three plus c is greater than 27?
snow_lady [41]
Hello!

You can break this down

12 times the sum of 3 and c

This can be written as 12(3 + c)

is greater than 27

12( 3 + c) > 27

This can be simplified to 36 + 12c > 27

The answer is 12(3 + c) > 27 or 36 + 12c > 27

Hope this helps!
