Jessie and Laura are trying to compute the area of a triangle with base 5cm and height, h. Jessie multiplies 1/2 by the product of 5 and h, while Laura multiplies 5 by h and then takes half the result.
a)Let J(h) be the function defined by Jessie's expression and L(h) be the function defined by Laura. Write expressions that define each function.
b)Are their functions equivalent? Justify answer by using definition of equivalent functions.
