Answer:
a)
Step-by-step explanation:
To find inverse:
replace f(x) with y: y = 2(x + 4)
Then switch y and x: x = 2(y + 4)
Finally make y the subject:
x = 2(y + 4)
x/2 = y + 4 (divide by 2)
x/2 - 4 = y (subtract 4)
So, the inverse is y = x/2 - 4
we know that
The <u>Triangle Inequality Theorem,</u> states that the sum of the lengths of any two sides of the triangle is greater than the length of the third side
so

we have
