Answer:
B. The other solution to function
is
.
Step-by-step explanation:
From Algebra, we remember that quadratic functions of the form
has solutions of the form:
, where both are complex if and only if
.
Hence, if one solution of the quadratic function is
, then the other solution is
. The correct answer is B.
Let t be the number of tolls they crossed.
Amount they spent at each toll = $1.75.
Amount they spent at gas station = $28.
Let C be the total amount they spent on gas and tolls.
If they crossed 1 toll, then
C = 28 + 1.75(1).
If they crossed 3 tolls, then,
C = 28 + 1.75(3)
If they crossed t tolls, then,
C = 28 + 1.75t
Here, the terms are 28 and 1.75t and the factors are 1.75 and t.
Your answer, in your set notation, is
{-2, 7}
