The inverse of the funtion <span> f(x) = 4x
</span><span> f(x) = 4x
y = 4x
Swap out x with y
x = 4y
x / 4 = y
y = x / 4

Looks like none of the answer you have given are correct.
</span>
It is function a the answer
Mid point is found by summation of x
Then divide by 2
And same for y
Since mid point for x is 8
So x+(-9) /2 = 8
X - 9 = 16
X=16+9
X= 25
Answer:
1
Step-by-step explanation:
what a tricky question.
pemdas- parenthesis, exponents, multiplication, division, addition, subtraction.
8/2(2+2)
add parenthesis first
8/2(4)
then multiply / distribute
2(4) is 8
finally
8/8 is 1
