Algebra Spiral

• A

• B

• C

• D

GRAPH the equation, then use MENU, TRACE, GRAPH TRACE to find the RANGE (y-values) of the graph. It's easier to to find the minimum or maximum value and check which answer choice is true.

• A

• B

• C

• D

Remember in order to check if a graph is a FUNCTION, it needs to pass the VERTICAL LINE TEST. The VERTICAL LINE TEST should pass through a graph ONLY ONCE for it TO BE A FUNCTION. If it crosses more than once it is not a function.

• H

• J

Information for graphing inequalities:

• A

• B

• C

• D

GRAPH each answer choice one by one and use MENU, TRACE, GRAPH TRACE and check to see if it has ZEROS (X-INTERCEPTS) at

x = -5 and x = 7.

• F

• G

• H

• J

You can use the DEFINE feature because it says the word EQUIVALENT.

x:=2

y:=3

Then type the original problem and type each answer choice and check which ones are equivalent.

• F

• G

• H

• J

Solve each equation for y by using RAILROAD TRACKS. Then, GRAPH both equation and use MENU, ANALYZE GRAPH, INTERSECTION to find the solution.

• A

• B

• C

• D

Solve the equation for y by using RAILROAD TRACKS. Then, GRAPH the equation and check which one MATCHES the answer choices provided.

• A

• B

• C

• D

GRAPH the given equation and MATCH it to the correct answer choice. Use the TRACE feature to verify exact points if needed.

To create an equation, start by writing y=mx+b on your paper. Then make sure to identify the slope by looking for keywords that indicate multiplication. Make sure to the change the x and y to the variables they provide.
