Which two sentences taken together provide the BEST evidence to support the idea that black holes are difficult to locate? Read the following sentences from the article. 1. This black hole is about 1,000 light-years away and each light-year is 5. 9 trillion miles (9. 5 trillion kilometers). 2. Astronomers theorize there are between 100 million and 1 billion of these small but dense objects in the Milky Way. 3. Usually, scientists can only spot them when they're gobbling up sections of a partner star or something else falling into them. 4. Astronomers think most black holes, including this newly discovered one, don't have anything close enough to swallow. Question 3 options: 1 and 2 1 and 4 2 and 3 3 and 4.

f(x) is going down by 4

step-by-step explanation:

(its either that or its going left by 4)

step-by-step explanation:

f(x)=2x^2 -1 

translation is a function transformation that transform the function in a way of translating. by translating the function its graph is moved  up an down. moving the function f(x) 2 units to the left will be the new function g(x) with the equation: g(x)=f(x+2)=2(x+2)^2 -1

what do u need to know

step-by-step explanation:

see attached

step-by-step explanation:

given the function as;

write the equation replacing f(x) with y

form   and fill a table containing values of y with corresponding values of x

you can take a range for   values of x as -3≤x≤3

solving for x=-3

for x=-2

repeat the same procedure to get the values of y for the remaining ,x=-1 to x=3

plot the values of y against values   of x and obtain the following graph
