TYPES OF FUNCTION

Question 1

IF F(X)=MX+B
M AND B ARE REAL NUMBERS
M AND F(X) ARE NOT BOTH EQUAL TO ZERO.
/ OR \

Answer 1

LINEAR FUNCTION

Question 2

FIND THE SLOPE M OF THE LINE USING THE SLOPE FORMULA.

Answer 2

M=Y2-Y1 / X2-X1

Question 3

SUBSTITUE ONE OF THE OPDERED PAIRS AND THE SLOPE (M) TO THE POINT SLOPE FORM.

Answer 3

Y-Y1 = M(X-X1)

Question 4

IF F(X) = MX+B
M = 0
B IS ANY REAL NUMBER
F(X) = B

Answer 4

CONSTANT FUNCTION

Question 5

IF F(X)=MX+B
M = 1
B = 0 
F(X) = X 
/

Answer 5

IDENTITY FUNCTION

Question 6

F(X) +AX2 + BX + C
A,B, AND C ARE REAL NUMBERS
A IS NOT EQUAL TO 0

THIS GRAPH IS ALSO CALLED PARABOLA.

Answer 6

QUADRATIC FUNCTION

Question 7

F(X) = X, FOR X _>0
F(X) = -X, FOR X

Answer 7

ABSOLUTE VALUE FUNCTION

Question 8

A “COMPOUND FUNCTION” WHICH IT IS DEFINED BY MULTIPLE SUB-FUNCTIONS.
/ / \

Answer 8

PIECEWISE FUNCTION

Question 9

F(X)= N(X) / D(X)
N(X) AND D(X) ARE POLYNOMIALS
D(X) IS NOT ZERO POLYNOMIAL.
-, ‘-

Answer 9
