Answer:

C. 27 $cm^{2}$

Step-by-step explanation:

For this problem find the area for the three individual segment then add them together.

Step 1: Find area of the rectangle

formula for area of a rectangle: bxh

b-base

h-height

3x6=18

Step #2: Find area of the triangle

Formula for area of a triangle: $\frac{1}{2} bxh$

b-base

h-height

$\frac{1}{2} (3x3)$ =1/2(9)=4.5

Step #3: Find the area of the triangles total

Because the two triangles have the same area you can just multiply the area of one of the triangles by 2

4.5x2=9

Step #4: Add all the areas together

rectangle+2 triangles

18+9=27

Consider the inverse function. Which conclusions can be drawn about f(x) = x2 + 2? Select three options. f(x) has a limited rang

PolarNik [594]

Answer:

f(x) has a limited range

f(x) has a maximum at the point (0, 2)

f(x) has a y-intercept at the point (0, 2).

Step-by-step explanation:

Given the function;

f(x) = x^2+2

The domain is the value of the input variables for which the function will exist. According to the expression given, the function exists on all real values of x. The same goes with range which deals with the output values. It also exists on all real values from 2 and above.

Hence f(x) have a limited range (since values less than 2 are not included compare to domain that exists on all real values) and does not have a restricted domain.

For the x intercept, x intercept occur at y = 0

substitute y = 0 into the function and get y

if y = f(x)

y = x^2+2

0 = x^2 + 2

x^2 = -2

x = 2i

Hence f(x) does not have an x-intercept of (2, 0)

For the y intercept, y intercept occur at x = 0

substitute x = 0 into the function and get y

if y = f(x)

y = x^2+2

y = 0^2 + 2

y = 2

Hence f(x) has a y-intercept at point (0, 2)

f(x) is at maximum if d(fx))/dx = 0

d(fx))/dx = 2x

since d(fx))/dx = 0

0 = 2x

x = 0

substitute x = 0 into the function

f(x) = x^2 + 2

y = 0^2+2

y = 2

Hence f(x) has a maximum at the point (0, 2)
