Given:

The function is

f(x)=4x+9

Domain = {-4, -2, 0, 2}

To find:

The range of the given function for the given domain.

Solution:

We know that domain is the set of input values and range is the set  of output values.

We have, f(x)=4x+9 and domain = {-4, -2, 0, 2}.

Putting x=-4 in the given function, we get

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

f(-4)=-16+9

f(-4)=-7

Putting x=-2 in the given function, we get

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

f(-2)=-8+9

f(-2)=1

Putting x=0 in the given function, we get

f(0)=4(0)+9

f(0)=0+9

f(0)=9

Putting x=2 in the given function, we get

f(2)=4(2)+9

f(2)=8+9

f(2)=17

The output values are -7, 1, 9, 17. So, the range of the function f(x) for the given domain is {-7, 1, 9, 17}.

Therefore, the correct option is D.

Small squares with sides 4 cm were cut from each of the corners of a square piece of cardboard. then it was folded into an open-
DENIUS [597]
Suppose the length of the card board was x cm by x cm
After squares of 4cm was cut from the corner, the dimension for the box will be:
length=(x-8) cm
width=(x-8) cm
height=4 cm
thus the volume will be:
V=length*width*height
V=4×(x-8)×(x-8)=144
x²-16x+64=36
this can be simplified to form a quadratic equation given by:
x²-16x+28=0
solving the quadratic equation we get:
x=2 or x=14
Thus we conclude that the original dimensions was:
length=14 cm ; width=14 cm

What is the value of the expression -225 divided by -15?<br><br> –25<br> –15<br> 15<br> 25
choli [55]
-225/-15 will give us a positive answer since we are dividing by two negative values, so we can rule out answers 1 and 2 first off.

then we solve to find the answer -225/1*-1/15 = 15 

hope this helps! thanks!
