- 3. Kiran wrote the expression x - 10 for this number puzzle: "Pick a number, add-2, and multiply by 5." Lin thinks Kiran made a mistake. a. How can she convince Kiran he made a mistake? Pich the nimber 2, you will get(2)-10=8 3 the way he said it, it would be: (2)-2- 5-0 The correct Way vould be to Write (x-3)s b. What would be a correct expression for this number puzzle? If you But 4. The output from a coal power plant is shown in the table:

c.35

step-by-step explanation:

8+13=21

21+8=29

29+6=35

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

take the logarithm of both sides (the base of the log doesn't matter):

apply the exponent property - this says that :

distribute the log terms on both sides:

group like terms together:

divide through both sides by the coefficient on :

you can do some additional rewriting here using the properties of the logarithm to simplify things if you like:
