Answer:

Option (C).

Step-by-step explanation:

Graphed function is,

f(x) = x² - 2x - 3

     = x² - 2x + 1 - 1 - 3

     = (x² - 2x + 1) - 4

     = (x - 1)² - 4

f(-2x) = (-2x)² - 2(-2x) - 3

        = 4x² + 4x - 3

        = 4(x² + x) - 3

        = 4[x² + 2(0.5)x + (0.5)²- (0.5)²] -3

        = 4(x + 0.5)² - 1 - 3

        = 4(x + 0.5)² - 4

        = 4[(x - 1) + 1.5]² - 4

Therefore, parent function 'f' will be a horizontal shrink by 4 units and  shifted 1.5 units to the left.

Option (C) will be the answer.

Vanyuwa [196]

Answer:

3

Step-by-step explanation:

(2x +1)/8 - (x-1)/3 = 5/24

multiple the 2x+1/8 by 3 and multiple (x-1)/3 by 8 then add them up

6x+3/24 - 8x-8/24 ➡ 6x-8x+11/24 = 5/24

➡ -2x+11 = 5

➡ -2x = 5-11

➡ x = 3
