F (x) = (3.x4 + 1)2
DONE

f(x)=(3.x4+1)2

Use the distributive property to multiply 3x  4   +1 by 2.

fx=6x  4  +2

The equation is in standard form.

xf=6x  4  +2

Divide both sides by x.

x  xf  =  x 6x  4  +2

Dividing by x undoes the multiplication by x.

 f=  x 6x  4 +2

​

Divide 6x  4 ​+2 by x.

 f=  x 2(3x  4 +1)

​  

This will help you if you are trying to solve for F. Hope this helped and hope this is correct.

e.

step-by-step explanation:

because there are always 10 numbers in a phone number.

problem:

f(x) = - 2/3x + 5; f(5/2)

substitute 5/2 in for x:

f(5/2) = -2/3(5/2) + 5

simplify the right side:

f(5/2) = -5/3 + 5

f(5/2) = 10/3

f(5/2) = 10/3

i hope this !
