Question 10 • Transition Mathematics for Seniors
Two functions are defined as shown. f of x is equal to negative 1 half x minus 2 g of x is equal to negative 1 Which graph shows the input value for which f of x is equal to g of x ?
Answer
A
Image with description A coordinate grid with two lines. One line labeled f of x passes through point negative 4 comma 0, point negative 2 comma 0, and point 0 comma negative 2. The second line is labeled g of x and passes through point negative 3 comma negative 1, point 0 comma negative 1, and point 3 comma negative 1.
B
Image with description A coordinate grid with two lines. One line is labeled f of x and passes through point negative 2 comma 3, point 0 comma 1 and point 2 comma negative 1. The second line is labeled g of x and passes through point negative 3 comma negative 1, point 0 comma negative 1, and point 3 comma negative 1.
C
Image with description A coordinate grid with two lines. One line labeled f of x passes through point negative 4 comma 2, point negative 2 comma 0, and point negative 1 comma 1. The second line is labeled g of x and passes through point negative 3 comma negative 1, point negative 1 comma negative 1, and point 1 comma negative 1. They intersect at point negative 1, negative 1.
D
Image with description A coordinate grid with two lines. One line labeled f of x passes through point negative 4 comma 1, point negative 2 comma 0, and point 1 point 5 comma negative 1. The second line is labeled g of x and passes through point negative 3 comma negative 1, point 0 comma negative 1, and point 1 point 5 comma negative 1. They intersect at point.
