2 Points In the straightedge and compass construction of the congruent angle below,
which of the following reasons can you use to prove that ZDEF LLJK?
E
F
O A. Draw a line through points D and Fand another line through points
Land K. Then ADEF ALJK by ASA, and DEF=ZLJK by CPCTC.
O B. Draw a line through points Dand Fand another line through points
Land K. Then ADEF ALJK by AAS, and ZDEF LLJK by CPCTC.
O C. Draw a line through points D and Fand another line through points
Land K. Then ADEFALJK by SSA, and DEF LLUK by CPCTC.
O D. Draw a line through points D and Fand another line through points
Land K. Then ADEF ALJK by SSS, and DEF=ZLJK by CPCTC. whats the answer

Which exponential function has an initial value of 2?

f(x) = 2(3x)

On a coordinate plane, an exponential function approaches y = 0 in quadrant 2 and increases into quadrant 1. It crosses the y-axis at (0, 0.5) and goes through (2, 2).

f(x) = 3(2x)

A 2-column table has 5 rows. The first column is labeled x with entries negative 2, negative 1, 0, 1, 2. The second column is labeled f (x) with entries one-eighth, one-fourth, one-half, 1, 2.

Step-by-step explanation:

let's cover over the formula of the vertex:

y = a(x – h)^2 + k

in this formula, (h,k) are the vertex, always remember that the positive or negative value of the vertex is based on the sign it has.

for example, if the vertex is -3,-6 then both the x and y value would have the positive sign attached to it and if it were a positive x and y value, then a negative sign would be attached to it.

with that being said, for our problem the x value is a positive one so we are looking for a number with a negative sign next to it, in this case the first and second choice.

however, for the first answer choice it isn't quite part of the formula so we know that the answer choice correctly displays the x value.

to confirm, we can see if the -1 fits correctly with the second answer choice, and as mentioned above a negative number will have a positive sign attached to it. so, for our problem we can see that -1 has been changed to +1, so we can confirm that the second answer choice is correct.

hence, our final answer is y=(x - 1)^2 + 1
