Answer:
B.
Step-by-step explanation:
Since 6 = 5r + 1, r = 1
As for s, if s is 2, then you can do
4 x 2 + 5 = 13 & 6 x 2 + 1 = 13
13 = 13
So B!
Hope that helps!
Here is how we get the answer....
First, replace f(x) with y . ...
Replace every x with a y and replace every y with an x .
Solve the equation from Step 2 for y . ...
Replace y with f−1(x) f − 1 ( x ) . ...
Verify your work by checking that (f∘f−1)(x)=x ( f ∘ f − 1 ) ( x ) = x and (f−1∘f)(x)=x ( f − 1 ∘ f ) ( x ) = x are both true.
3 the answer is 3 because if you move 7 units over you get 3
Answer:
C. G(x) has no root.
Step-by-step explanation:
A is wrong as the graph shows one minimum.
B is wrong as x approaches negative infinity, F(x) will approach infinity; not negative infinity.
D is wrong as it does not have 4 real roots.
Only answer left is C and it is true that G(x) has no root.
Step-by-step explanation:
First, we need to find that top angle, which we'll call angle x. We can say 26 is the hypotenuse, and 12 is the adjacent, so we know that:

Let's solve this, to find X:

Now that we know what X is, we can use trig to find the missing side, which we'll call y. 48 is the adjacent, and y is the hypotenuse, therefore:

To find y, let's rearrange:

And now let's figure out calculate the value of y (I'm leaving the value of X as just X for the equations, but you will need it to calculate first):
