Given the parent function of f(x) = x4, what change will occur when the function is changed to f(−2x)?

Nikitich [7]

Answer:

Graph will open same way and is narrower.

Step-by-step explanation

If: f(x)= x^4

f(-2x)= (-2x)^4

Negative sign usually flips the graph and make it open to the opposite direction. In this case since the function is to the 4th degree and the negative sign is included. The negative is basically ignored.

The term in front of x (a) determines how wide the graph opens. The bigger the a value the faster the slope increases so the narrower the graph opens.

Think if the slope is 4 vs 1/4.

Hope this helps

Solve the system by elimination. − 2 x + 2 y + 3 z = 0 − 2 x − y + z = − 3 2 x + 3 y + 3 z = 5

taurus [48]

Answer:

$x=1, y=1, z=0$

Step-by-step explanation:

we have

$-2x+2y+3z=0$ ----> equation A

$-2x-y+z=-3$ -----> equation B

$2x+3y+3z=5$ ----> equation C

adds equation A and equation C

$-2x+2y+3z=0\\2x+3y+3z=5\\-------\\2y+3y+3z+3z=0+5$

$5y+6z=5$ -----> equation D

adds equation B and equation C

$-2x-y+z=-3\\2x+3y+3z=5\\--------\\-y+3y+z+3z=-3+5$

$2y+4z=2$ -----> equation E

we have the system

$5y+6z=5$ -----> equation D

$2y+4z=2$ -----> equation E

Multiply equation E by -1.5 both sides

$-1.5(2y+4z)=-1.5(2)$

$-3y-6z=-3$ -----> equation F

adds equation D and equation F

$5y+6z=5\\-3y-6z=-3\\---------\\5y-3y=5-3\\2y=2\\y=1$

<em>Find the value of z</em>

substitute the value of y in equation E (or substitute in equation D)

$2(1)+4z=2$

$2+4z=2$

$4z=0$

$z=0$

<em>Find the value of x</em>

substitute the value of y and z in equation A (or equation B or C)

$-2x+2(1)+3(0)=0$

$-2x+2=0$

$-2x=-2$

$x=1$

therefore

The solution of the system of equations is

$x=1, y=1, z=0$

What is the measure of

Novosadov [1.4K]

Answer:

Step-by-step explanation:

From your choices, it looks like you want m<A

Solution

<C = 46° The triangle is isosceles. The two marked sides are equal.

<A + <B + <C = 180l All triangles have interior angles = 180

<A + 46 + 46 = 180 Combine

<A + 92 = 180 Subtract 92

<A = 180 - 92

<A = 88

The second of two numbers is 6 times the first. their sum is 84. find the numbers

ddd [48]

X = first numbery = second number Since the second of there two numbers is 6 times the first, this means y equals 6 times x. Therefore, the equation formed will be y = 6x. The second condition is that the same of the two numbers 77. Therefore:x + y = 77Since y = 6x, we can substitute y for 6x and get x + 6x = 77. Simplifying this we get 7x = 77.Therefore, x = 11. We found out the first number, x, equals 11. To find out what y is, we just plug it back into the equation x + y = 77. Therefore, 11 + y = 77 --> y = 66 Answer: The first number equals 11, and the second number equals 66.
