1 Introduction to Functions LEARNING OBJECTIVE: Identify elements of functions. .00 For an ordered pair {:-:'3',_'!x"':' in a relation, the _';.--" element represents the b.) domain c.) range d.) function 2 - Evaluating functions LEARNING OBJECTIVE: Evaluate a function for a given value. If f(x) = 3x2 -5x +4, then f( - 2) = O a.) - 18 O b.) 26 O c.) 2 O d.) 63 Adding and Subtracting Functions LEARNING OBJECTIVE: Add or subtract two functions. .00 If filo} = 2.5:. + 5 and gift} = :-: 2 'l , then fl: 3C1+gi2i = 4 - Multiplying and Dividing Functions LEARNING OBJECTIVE: Multiply or divide two functions. If f(x) = x -2 and g(x) = 2x -6, then g(4) / f(3) = ( a.) 0 O b.) 2 O c.) 1 ( d.) 36 - Function of a Function LEARNING OBJECTIVE: Evaluate a composite function. If f(x) =2x -2 and g(x) =x2+1, then f(g( - 2)) = _ O a.) - 8 O b.) - 12 O c.) 4 O d.) 87 Inverse Functions LEARNING OBJECTIVE: Identify the steps to find the inverse of a given function. .00 Win; is added to 4 and then multiplied by 2, then the function is fl:.:~::l = Elli-z +4). What are the steps to nd the inverse to this function? a.) Divide by 2, then subtract 4 hi.) Add 2, then multiply by 4 c.) Multiply by 4, then add 2 d.) Subtract 4, then divide by 2 8 Finding the Inverse of a Function LEARNING OBJECTIVE: Determine the inverse of a given function. .00
