How does the graph of the function g(x) = 2x – 4 differ from the graph of f(x) = 2x
Lena [83]

9514 1404 393

Answer:

  the y-intercepts differ

Step-by-step explanation:

The x-coefficient is the same for each function, so parallel lines are described. The function g(x) has a y-intercept of -4; f(x) has a y-intercept of 0.

The graphs differ in their intercepts.

__

<em>Additional comment</em>

g(x) can be considered to be a translation downward of f(x) by 4 units. The same graph of g(x) can be obtained by translating f(x) to the right by 2 units. That is, both the x-intercepts and y-intercepts differ between the two functions.

False because you walk both the sides so you would have to do 360x2 added to 160x2

Solve the equation by completing the square. Round to the nearest hundredth if necessary. x2 – x – 7 = 0
Tanzania [10]
2x-x-7=0

3x-7=0

add 7 to 7 and 0, so then we cross out 7-7, and then

3x=7, bc u change the subtraction to addition, sr if thst doesn't make sense but 3x=7 is the answer

What is the value of f ( − 3a ), if f ( x ) = 2x 2 + 4x ?
gogolik [260]

Answer:

d. 18a² - 12a

Step-by-step explanation:

f(x) = 2x² + 4x

f(-3a) = 2(-3a)² + 4(-3a)

2(-3a)² + 4(-3a)

2(9a²) + (-12a)

18a² - 12a
