Y= -x^{2}+4x+6

Turning points occur when the gradient of the function is zero.
\frac{dy}{dx} =-2x+4
Then equating to 0;
-2x+4=0
-2x=-4
x=2

From the fucntion, when x=2 ;
y=-(2)^{2}+4(2) +6
y=-8+8+6
y=6
Turning point;
(2,6)

A landscaper has built a U-shaped raised bed in a vegetable garden as shown in the figure. How many cubic yards of soil should b
zaharov [31]

First calculate the area of the shaded region by considering the U-shaped bed as formed by three rectangles, as follow:

where the lengths of the sides of the rectangles corresponds with the dimensions of the U-shaped bed.

Then, for the area of the figure, use the formula for the area of a rectangle, for all three rectangles, as follow:

A = 5*18 + 3*20 + 5*18

A = 90 + 60 + 90

A = 240

Then, the area is 240 in^2

Next, convert the previous result to yd^2. Use the equivalence 1 yd = 36 in:

240in^2\cdot\frac{(1yd)^2}{(36in)^2}=0.185yd^2

Now, to find the volume convert 30 in to yards:

30in\cdot\frac{1yd}{36in}=0.83yd

Finally, multiply the previous result by the area of the figure:

0.185yd^2\cdot0.83yd=0.154yd^3

If f(x)= 2(3x²-2x+2). Find:<br><br>A) f(x+1)<br>B) f(3)​<br>C) f(y-2)
ExtremeBDS [4]
A) f(x+1) = 6x^2 + 8x + 6
1) substitute the value of x as (x+1)
2) 2(3(x+1)^2 -2(x+1) +2)
3) 6(x^2 + 2x + 1)
4) 6x^2 + 8x + 6

B) f(3) = 46
1) simplify the expression first
2) 6x^2 -4x + 4
3) Now just substitute 3: 6(3)^2 -4(3) + 4
4) 6•9 - 12 + 4 = 46

I hope this helps :)
