How can you tell if 2 functions are inverses of eachother

1 answer:

Remember, if the two graphs are symmetric with respect to the line y = x (mirror images over y = x ), then they are inverse functions. But, we need a way to check without the graphs, because we won't always know what the graphs look like! then f(x) and g(x) are inverse functions.

Check each equation whose graph is the line that contains the points (4, –7) and (1, 5). y = –4x + 9 y = –4x – 23 y – 1 = –4(x –

Dave has 10 poker chips, 6 of which are red and the other 4 of which are white. Dave likes to stack his chips and flip them over

Marina86 [1]

The number of 10 chips stacks that Dave can make if two stacks are not considered distinct is 110.

The solution

To get the symmetric stacks, one has to subtract the symmetric stacks to know the ones that are asymmetric.

The symmetric are flipped. Given that they are double counted what we have to do is to divide through by 2.

6/2 = 3

10/2 = 5

4/2 = 2

1/2(10C6) - (5C3) + (5C3)

0.5(210-10+10)

= 110

Y=x+1 y=x^2-1 please help i don't understand

ololo11 [35]

ANSWER

The solution is

$(x=1,y=2),(x=2,y=3)$

EXPLANATION

We have

$y=x+1---(1)$

and

$y=x^2-1---(2)$

Let us substitute equation (1) in to equation (2). This gives us,

$x+1=x^2-1(2)$

We rewrite this as a quadratic equation as the highest degree is 2.

$x^2-x-1-1=0$

This implies that

$x^2-x-2=0$

we factor to obtain,

$x^2+x-2x-2=0$

$x(x-1)-2(x-1)=0$

$(x-1)(x-2)=0$

This means,

$(x-1)=0\:\: or\:\:(x-2)=0$

$x=1\:\: or\:\:x=2$

We substitute this values into any of the above equations, preferably equation (1)

When, $x=1$ , $y=1+1=2$

When, $x=2$ , $y=2+1=3$

The solution is

$(1,2),(2,3)$
