Create and Graph Equations in Two or More Variables
Standard A.CED.2 – Create equations in two or more variables to represent relationships between quantities; graph equations on coordinate axes with labels and scales.
a. Focus on applying linear and simple exponential expressions. (A1, M1)
b. Focus on applying simple quadratic expressions. (A1, M2)
c. Extend to include more complicated function situations with the option to graph with technology. (A2, M3)
Vocabulary for this standard:
This is introduced in module one
portion of the EngageNY curriculum and repeated multiple times throughout the curriculum.
A base is a number or expression being multiplied in an exponent
An exponent is a number that describes how many times to use the number in a multiplication.
A coefficient is a number used to multiply a variable.
A negative exponent expresses that the base is the denominator of a fraction instead of the numerator
The multiplicative property of exponents says that when you multiply powers with the same base you just have to add the exponents
The division property of exponents says that when you divide powers with the same base you just have to subtract the exponents
The power of a power property says that when you raise an exponent to another power, you just have to multiply the exponents
