Two quadratic functions are shown.
slava [35]

Answer:

Option (1) is the correct option.

Step-by-step explanation:

Function 1,

f(x) = 4x² + 8x + 1

     = 4(x² + 2x) + 1

     = 4(x² + 2x + 1 - 1) + 1

     = 4(x² + 2x + 1) - 4 + 1

f(x) = 4(x + 1)² - 3

This graph opens up with the vertex or minimum point at (-1, -3)

So, the minimum value of the function is (-3) at x = -1.

Function (2)

From the given table minimum value of the function is 0 at x = -1 or minimum point as (-1, 0)

Therefore, Function 1 has the least minimum value and its coordinates are (-1, -3)

Option (1) is the correct option.

Conver the equation y=2 to polar form. Then solve the resulting equation for r. <br> Thanks :)
maksim [4K]
This is something to memorize

y = r*sin(theta)

so if y = 2, then 

2 = r*sin(theta)

Divide both sides by sin(theta) to get

r = 2/sin(theta)
r = 2csc(theta)

Someone help please

Steps to finding the line in the diagram with the format 'ax + by = c

1. Find the slope

  • To find the slope, we need any two points on the line --> (0,4) and (3,0)

                  Slope = \frac{y2-y1}{x2-x1} =\frac{4-0}{0-3} =-\frac{4}{3}

2. Set up, with any one point on the line and the slope, in point-slope form

   

        (y-y0)=m(x-x0)\\(y-4)=-\frac{4}{3} (x-0)\\y-4 = -\frac{4}{3} x\\\frac{4}{3}x+y = 4

<u>Answer</u>: \frac{4}{3}x+y = 4

Hope that helps!
