F(x) =2x+4 translate 7 units left

Step-by-step explanation:

Translate 7 units left

When a function f(x) is translated b units to the left, the resulting function is:

In this case:

becomes

Calculating

So:

by definition, an arc subtended by a central angle of some given measure has the same measure. so .

set each factor equal to 0

4x-3 = 0

2x-1 = 0

solve for x.

4x-3=0

4x=3

x= 3/4

solve for x. 

2x-1= 0

2x= 1

x= 1/2

eventually after a few more steps, your answer should be 1/2 is less than or equal to x and 3/4 is greater than or equal to x
