Find each key feature of the function shown in the graph.

in the xy graph the range of the x axis is negative 8 to 9 by increment of two. the range of the y axis is negative 8 to 8 by increment of two. on the graph there are open circles at the point (-8, 4) and (4.5, 2). there are closed points at (-4,-4) and (9.5, -2). all these points are joined by solid line.

range =

domain =

is the function positive or negative over the interval (–8, –6)?

let soccer = x and golf = y

part a

1st equation: x + y = 125

2nd equation: x = y +45

part b

replace x in the 1st equation with the 2nd one:

y + 45 + y = 125

simplify:

2y + 45 = 125

subtract 45 from each side:

2y = 80

divide both sides by 2:

y = 80/2

y = 40

she plays golf for 40 minutes.

part c

no because she plays soccer for 45 minutes longer than golf 40 +45 =   85 minutes, not 80 minutes.
