Consider the function f(x)=-3x^2 +7x -k. [3 Marks] a) For what values of k will the function have no zeros? b) For what values o
Anna35 [415]

Answer: a) k >4.08

b) k = 4.08

c) k<4.08

Step-by-step explanation:

Since we have given that

f(x)=-3x^2+7x-k

a) For what values of k will the function have no zeros?

It mean it has no real zeroes i.e. Discriminant < 0

As we know that

D=b^2-4ac

Here, a =-3

b = 7

c = -k

So, it becomes,

D

b) For what values of k will the function have one zero?

It means it has one real root i.e equal roots.

So, in this case, D = 0

So, it becomes,

D=b^2-4ac=0\\\\D=7^2-4\times -3\times -k=0\\\\49-12k=0\\\\49=12k\\\\k=\dfrac{49}{12}\\\\k=4.08

c) For what values of k will the function have two zeros?

It means it has two real roots.

In this case, D>0

So, it becomes,

D=7^2-4\times -3\times -k>0\\\\49-12k>0\\\\-12k>-49\\\\12k

Hence, a) k >4.08

b) k = 4.08

c) k<4.08

If y is directly proportional to x² and y=2 when x=3 Find the value of y when x=6<br>Please Help
OlgaM077 [116]

Answer:

y = 8

Step-by-step explanation:

Given that y is directly proportional to x² then the equation relating them is

y = kx² ← k is the constant of variation

To find k use the condition y = 2 when x = 3, then

2 = k × 3² = 9k ( divide both sides by 9 )

\frac{2}{9} = k

y = \frac{2}{9} x² ← equation of proportion

When x = 6, then

y = \frac{2}{9} × 6² = \frac{2}{9} × 36 = 2 × 4 = 8
