The ? Is 3
As 4^3 = 64
4x4x4= 64
Answer:
Step-by-step explanation:
Use the Quadratic formula:
You can identify that, in this case:
Now you need to substitute these values into the formula:
Remember that:
Therefore,rewriting and simplifying, you get:
Then, you get the following roots:
Answer:
9
Step-by-step explanation:
not 9
The inverse function of the given function y = x² + 4 will be y = √(x - 4).
<h3>What is the inverse function?</h3>
Let the function f is given as
y = m(x + a) + c
Then the inverse function of the function f will be given by swapping x with y and y with x.
The definition of simplicity is making something simpler to achieve or grasp while also making it a little less difficult.
The function is given below.
y = x² + 4
The inverse function of the function y = x² + 4 is given as,
Replace x with y and y with x, then we have
x = y² + 4
Solve the equation for y, then the equation is rewritten as,
x = y² + 4
y² = x - 4
y = √(x - 4)
The inverse function of the given function y = x² + 4 will be y = √(x - 4).
More about the inverse function is given below.
