Answer:
f^-1 (x) = 2X + 8
Step-by-step explanation:
Let's make f(x) = y
Y = X/2 - 4
So to find the inverse, switch the y with the x like so:
X = Y/2 - 4 (isolate the Y value)
X + 4 = Y/2 (multiply both sides by 2)
2(X + 4) = Y
Y = 2X + 8
So f^-1 (x) = 2X + 8
Answer:
32 cm²
Step-by-step explanation:
6*4+ 1/2*4*4= 32 cm²
I=p*r*t
multiply 8,000*.6*1
I=4800
Answer = - 2x + 2y = - 8
Because when the x intercept is 4 the y intercept is 0 so if you put these into the equation
-2x4 + 0 = - 8
-8 = - 8
Both sides of the equation are equal
