F(x) = 1 / 2 g(x) = x - 4 Can you evaluate (g o f) (0)? Explain why or why not.

Vitek1552 [10]

For this case we have the following functions:

$f (x) = \frac {1} {2}\\g (x) = x-4$

We must find $(g_ {o} f) (x)$ . For definition of composition of functions we have to:

$(g_ {o} f) (x) = g (f (x))$

So:

$g (f (x)) = \frac {1} {2} -4 = \frac {1-8} {4} = \frac {-7} {4} = - \frac {7} {4}$

Then, for any value of "x", the composite function has a value of $- \frac {7} {4}$ .

Thus, $(g_ {o} f) (0)$ cannot be evaluated, it will always be obtained $- \frac {7} {4}.$

ANswer:

For any value of "x", the composite function has a value of $- \frac {7} {4}.$

Solve the linear system

Aleks04 [339]

1.5x+4y=16
5x+4(-16)=16
5x-64=16
5x=80
x=16

2.3x+6y=15
-2x+3y=-3

Multiply the 2nd equation by 2

3x+6y=15
-4x+6y=-6
7x=9
x=9/7

3x+6y=15
3(9/7)+6y=15
27/7+6y=15
6y=78/7
y=78/42 or 39/21 or 13/7

3.7y = -14x + 42
7y = 14 x + 14

-14x+42=14x+14
-28x=-28
x=1
