Number 12 what do you think we do first
You will substitute in 1.2 for y because it is the output value.
1.2 = x - 0.4
1.6 = x
So the input value for the output value of 1.2 is 1.6.
Answer: B
Step-by-step explanation:
The converse means X --> Y , so Y --> X.
In other terms, you just need to reverse the terms and review that it turns out correct. In answer B, it does that just right.
One way in which to do this problem is to find the inverse function of G(x) first. Another, faster, method is to look at G(x) = 3x + 1. Find the x value for which y = 1:
1 = 3x + 1. Then x must equal 0. If (0, 1) satisfies G(x) = 3x + 1, then (1, 0) satisfies the inverse function of G(x) = 3x + 1.
Thus, the value of the inverse function with input 1 is 0.
Step 1: Replace "G(x)" with y.
Step 2: Solve the resulting equation for x.
Step 3: Replace x with y and y with x.
-1
Step 4: Replace this "y" with G (x).
Now replace "x" with "1".
Answer:
<h2> f(-7) = 249 </h2>
Step-by-step explanation:
To find f(-7) , substitute the value of x that's - 7 into f(x). That is for every x in f(x) replace it with - 7
We have
We have the final answer as
<h3>f( -7) = 249</h3>
