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)
Since the limit of f(x) is non-zero, the limit distributes over the quotient and
