What is the general form of a linear function?

• y = ax^2 + bx + c

• y = mx + b

• y = ab^x

• y = a/x + b

What shape does a quadratic function typically have when its coefficient 'a' is positive?

How can you distinguish an exponential function from a power function based on the placement of 'x'?

• 'x' is the base in exponential functions

• 'x' is the exponent in exponential functions

• 'x' is multiplied by a constant in exponential functions

• 'x' is added to a constant in exponential functions

What is the equation for a power function?

• y = a/x + b
