<span>f(x) = 0.3(4)x ------> f(x)=1.2x
As,
f(x)=y
So,
y=1.2x
re arranging x and y:
x=1.2y
y=1.2/x
f(-1)x= x/1.2
putting x=6:
f(-1) 6 = 6/1.2
</span><span>f(-1) 6 = 5</span>
-1 1/8 because -9/8 is equal to so just make it a improper fraction, pretend the negative is not there then add the negative at the end
-hope this helps :D
I^22 equals to -1 since i^2 is negative one
52° would be the value of x
