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

Lena [83]

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.

1/3(33x +15) - 1/3 ( 21x +18) =10

inn [45]

      ¹/₃(33x + 15) - ¹/₃(21x + 18) = 10
¹/₃(33x) + ¹/₃(15) - ¹/₃(21x) - ¹/₃(18) = 10
   11x + 5 - 7x - 6 = 10
   11x - 7x + 5 - 6 = 10
      4x - 1 = 10
      + 1   + 1
   4x = 11
