Answer:
(a) no
(b) -1, (2, -1)
(c) 4, (4, 7)
(d) no
Step-by-step explanation:
<h3>(a)</h3>
You can check by using x=3 in the function.
f(3) = 4(3) -9 = 12 -9 = 3 . . . . not -3
The point (3, -3) is not on the graph.
__
<h3>(b)</h3>
Put x=2 into the function and evaluate:
f(2) = 4(2) -9 = 8 -9
f(2) = -1
The point (2, -1) is on the graph.
__
<h3>(c)</h3>
Put f(x) = 7 into the equation and solve for x.
7 = 4x -9
16 = 4x
4 = x
The point (4, 7) is on the graph.
__
<h3>(d)</h3>
no, see part (b)
You need to add them all up
Ok for the first one. since 24/4 is 6 the first answer is correct but since each walk is $6 and 5 walks would get her $30. both answers are correct
then for the second one, you would start with 3 miles per 1 hour (because 6/2 is 3) and then the answer would be 9 miles in 3 hours because if she did 6 miles in 2 hours, 6+3 would be nine. so the last one is correct
