Okay so i know g(x)= 3k-2x² and g(-3)=-6

USPshnik [31]

g(x)= 3k-2x²

g(-3)=-6 ____(1)

So, using (1),

-6 = g(-3)

=> -6 = 3k - 2(-3)²

=> -6 = 3k - 2(9)

=> -6 = 3k - 18

=> -6 +18 = 3k

=> 12 = 3k

=> 12/3 = k

=> 4 = k

Now, you can find g(n) for any number n, as now we know the value of k. Specify the value of x, if you want to know what is g(x).

5 What is the range of y = -x2 - 2x + 3? Ax<4 B x2-4 c y<4 Dy2-4

Vesnalui [34]

Answer:

$y\leq 4$

Step-by-step explanation:

we have

$y=-x^{2}-2x+3$

This is a vertical parabola open downward (the leading coefficient is negative)

The vertex is a maximum

The vertex is the point (h,k)

The range of the function is the interval (-∞,k]

$y\leq k$

Convert the quadratic equation in vertex form

Factor -1 leading coefficient

$y=-(x^{2}+2x)+3$

Complete the square

$y=-(x^{2}+2x+1)+3+1$

$y=-(x^{2}+2x+1)+4$

Rewrite as perfect squares

$y=-(x+1)^{2}+4$

The vertex is the point (-1,4)

therefore

The range is $y\leq 4$

Answer:

Step-by-step explanation:

The answer is B because 3/5 of 1/2 is less than 1/2. The equation that represents this problem is

3/5 x 1/2 = 3/10

3/10 < 1/2

Therefore, 3/5 is less than 1/2!
