Answer: To find the inverse of the function, we need to make x as a function of y and at the final step make a switch between x and y (i.e. make x as y and y as x)
y = x² + 4x + 4 ⇒⇒⇒ factor the quadratic equation
y = (x+2)(x+2)
y = (x+2)² ⇒⇒⇒ take the square root to both sides
√y = x+2
x = √y - 2 ⇒⇒⇒ x becomes a function of y
final step:
∴ y = √x - 2 ⇒⇒⇒ the inverse of the given function
So, as a conclusion:
f(x) = y = x² + 4x + 4 ⇒⇒⇒ the given function
f⁻¹(x) = y = √x - 2 ⇒⇒⇒ the inverse of the given function
Thank you so much friend.
I think a advantage of this will be that we will be able to tell our grandchildren about how we survived the pandemic, just like our grandparents talk about World War. Lol.
Answer:
8+2x
Step-by-step explanation:
Combine Like Terms:
<u>1</u><u>6</u><u>-</u><u>8</u>+5x-3x
8+<u>5</u><u>x</u><u>-</u><u>3</u><u>x</u>
8+2x
My answer is 13+16+19 because we’re are adding 3 each time
Possibly 230 minutes?? dont quote me on that lol
