Linear Function: F(x)=mx+b - correct answer - Domain and range are all real numbers -Graph is nonvertical line with slope=m y intercept=b -m and b are real numbers Identity Function: F(x)=x - correct answer -Special type of linear function -Domain and range are all real numbers -Graph is a line with slope of m=1 and y-intercept=0 -The line consists of all points for which the x-coordinate equals the y-coordinate Constant Function: F(x)=b - correct answer - Domain is the set of all real numbers and range is the set consisting of a single number b. -Graph is a horizontal line with slope m=0 y-intercept of b Square Function: F(x)=x^2 - correct answer -Domain is the set of all real numbers; its range is the set of nonnegative real numbers. -The intercept of the graph is (0,0) Cube Function: F(x)=x^3 - correct answer - Domain and range are a set of all real numbers. -The intercept of the graph is (0,0) Square Root Function" F(x)=√x - correct answer -Domain and range are the nonnegative real numbers. -The intercept of the graph is at (0,0) Cube Root Function: F (x)=3√x - correct answer -Domain and range are the set of real numbers. -The intercept of the graph is (0,0) Reciprocal Function:F(x)=1/x - correct answer -Domain and range are set of all nonzero real numbers. -The graph has no intercepts. Absolute Value Function: F(x) =IxI - correct answer -Domain is the set of all real numbers; its range is the set of all nonnegative real numbers. -The intercept pf the graph is (0,0) -If x=0 then f(x)=x, and the graph of f is part of the line y=x; if x is less then 0, then f(x)=-x and the graph of f is part of the line y=-x
