Question 9

If f of x is equal to 1 over x and g of x is equal to x plus 3 , which of the following is the graph of open paren f circ g close paren times x ?

Revolt · Accepted Answer

B: Image with description On a coordinate plane, the scale on the x axis range from negative 8 to 2 in increments of 1, and the scale on the y axis range from negative 5 to 5 in increments of 1. The graph is made up of two different curves that do not meet. One of the curves opens up and to the right in quadrants 1 and 2 and passes through the point (negative 2 comma 1). The curve crosses the x axis at nonsignificant numbers. The other curve opens down and to the left in quadrant 3 and passes through the point (negative 4 comma negative 1).

Question 10

If f of x is equal to 1 over x and g of x is equal to x minus 2 , which of the following is the graph of open paren f circ g close paren times x ?

Revolt · Accepted Answer

D: Image with description On a coordinate plane, the scale on the x axis range from negative 3 to 7 in increments of 1, and the scale on the y axis range from negative 5 to 5 in increments of 1. The graph is made up of two different curves that do not meet. One of the curves opens up to the right in quadrant 1 and passes through the point (3 comma 1). The other curve opens down and to the left in quadrants 3 and 4 and passes through the point (1 comma negative 1). The curve crosses the y axis at nonsignificant numbers.
