What is the range of the function f(x) = 4x + 9, given the domain D = {-4, -2, 0, 2}?

♥️♥️♥️♥️♥️♥️♥️♥️♥️♥️♥️♥️♥️♥️

$f( - 4) = 4( - 4) + 9 = - 7$

_________________________________

$f( - 2) = 4( - 2) + 9 = 1$

_________________________________

$f(0) = 4(0) + 9 = 9$

_________________________________

$f(2) = 4(2) + 9 = 17$

_________________________________

Thus ;

R = { - 7 , 1 , 9 , 17 }

The correct answer is (( D )) .

.. pls help me....!!!!! Determine whether the point (-2,4) satisfy y<3x+5,y=3x+5 or y >3x+5..

nasty-shy [4]

Answer:

$y > 3\cdot x + 5$

Step-by-step explanation:

Let $A(x,y) = (-2,4)$ and $y = 3\cdot x + 5$ . Now we evaluate the given function at $x = -2$ :

$y = 3\cdot x + 5$ (1)

$y = 3\cdot (-2)+5$

$y = -6 +5$

$y = -1$

Which means that $y$ is less than the y-component of A. Therefore, the right answer is $y > 3\cdot x + 5$ .

I really need help please

GalinKa [24]

Answer:

B, C, E, F

Step-by-step explanation:

The following relationships apply.

the diagonals of a parallelogram bisect each other
the diagonals of a rectangle are congruent
the diagonals of a rhombus meet at right angles
a rectangle is a parallelogram
a parallelogram with congruent adjacent sides is a rhombus

CEDF has diagonals that bisect each other, and it has congruent adjacent sides. It is a parallelogram and a rhombus, but not a rectangle. (B and C are true.)

ABCD has congruent diagonals that bisect each other. It is a parallelogram and a rectangle, but not a rhombus. (There is no indication adjacent sides are congruent, or that the diagonals meet at right angles.) (E and F are true.)

The true statements are B, C, E, F.
