Step-by-step explanation:
so,
y = -9x + 2
now we need to transform this equation that actually x is calculated out of y.
and then, at the end, to make the inverse function a formally correct function, we rename x to y and y to x.
so,
y = -9x + 2
y - 2 = -9x
x = -(y - 2)/9 = (-y + 2)/9
=> for a formal function definition
y = (-x + 2)/9

Answer:
(-1.5,-16)
(1,4)
(2.5,-3)
Step-by-step explanation:
Over the interval (-3,0], the local minimum is (-1.5,-16).
Over the interval [0,3], the local maximum is (1,4).
Over the interval [0,57 , the local minimum is (2.5,-3).
Answer:
The answer is 37 200.
Step-by-step explanation:
The steps are :
x² - y² = (x + y)(x - y)
193² - 7² = (193 + 7)(193 - 7)
= (200)(186)
= 37 200
