Answer:
The value of k is 1.
Step-by-step explanation:
x – 1 is a factor of f(x)
This means that:
x - 1 = 0
x = 1
That means that when . We use this to find the value of k.
f(x) = 3x^3 - 4x + k
The value of k is 1.

Answer:
y is also doubled.
Step-by-step explanation:
Direct proportionality between and
means that
or
,
which indicates a linear relationship between and
because they are related by a constant.
Therefore, if x is doubled, then the new value of is
The new value of is 2 times the previous; therefore,
is doubled as
is doubled.
In a quadratic function, the leading coefficient is
, i.e. the coefficient of
, and the constant term is
, i.e. the coefficient without any power of
.
So, if you want leading coefficient 2 and constant term -3, your function needs to be like
for any value of . Among your options:
- The first is not a quadratic (it starts with
)
- The second has leading term -3 and constant term 2
- The third is not a quadratic (same as the first)
- The last is correct.
