How is the graph of y = –x2 – 1 different from the graph of y = –x2?

Every transformation like

translated the graph vertically, k units up if k is positive, k units down if k is negative.

So, in your case, we have that is the same graph as , except it's shifted 1 unit down.

d≈7.07in

step-by-step explanation:

first, you divide the triangle in two, tô form a retangle triangle. after, using pythagoream theorem:

18^2 = 14^2 + (x/2)^2

(x^2/4) + 196 = 324

x^2/4 = 324 - 196

x^2/4 = 128

x^2 = 512

x = √512

x = √2^9

x = 16√2 cm

i hope i you.
