Answer:

Yes, the given relation is a function.

Step-by-step explanation:

Given the quadratic function, y = (x + 1)², and the domain of {-2, -1, 0, 1, 2, 3}:

By definition, a function is a relation in which no two ordered pairs have the same first component (x-values) and different second components (y-values). Observing the given domain, there are no repeating input values.

Therefore, the correct answer is that the relation is a function.

Which graph represents the function of f(x) 9x^2 -36 / 3x + 6

Finger [1]

Answer:

The graph in the attached figure

Step-by-step explanation:

we have

$f(x)=\frac{9x^{2}-36}{3x+6}$

Remember that the denominator cannot be equal to zero

The value of x cannot be equal to x=-2

Simplify the numerator

$9x^{2}-36=(3x+6)(3x-6)$ ----> by difference of squares

substitute

$f(x)=\frac{(3x+6)(3x-6)}{3x+6}$

simplify

$f(x)=3x-6$

The domain is all real numbers except the value of x=-2

The y-intercept is the point (0,-6) ---> value of y when the value of x is equal to zero)

The x-intercept is the point (2,0) ---> value of x when the value of y is equal to zero)

therefore

The graph in the attached figure

Find the area of the hexagon. A) 36 in2 B) 52 in2 C) 78 in2 D) 144 in2

s2008m [1.1K]

Answer: C) 78 in2

Step-by-step explanation:

The polygon is divided into two trapezoids with equal measurements.

Area of a trapezoid:

(b1 + b2)h

Since the area of the hexagon equals the area of two trapezoids with equal measurements, do not multiply by 1/2.

(b1 + b2)h

(10 + 16)3

26(3)

78 in2

I will mark brainliest to whoever gets this answer! Please help!

Answer:

20 yd²

Step-by-step explanation:

This problem is really easy once you break it down!

First, find the area of the triangle.

$A = \frac{1}{2}bh$

b = 5 + 3 = 8

h = 4 + 4 = 8

$A = \frac{1}{2}*8*8$

$A = 32$

Now find the area of the square.

$A = lw$

$A = 4*3$

$A = 12$

The last step is to subtract.

Area of triangle - area of rectangle =

32 - 12 = 20

20 yd²

Hope this helped! :)
