Answer:

The missing coefficient is -8

Step-by-step explanation:

Let

a------> the missing coefficient

we have

$ay^{2}-[-5y-y(-7y-9)]-[-y(15y+4)]=0$

$ay^{2}-[-5y+7y^{2}+9y]-[-15y^{2}-4y]=0\\ \\ ay^{2}+5y-7y^{2}-9y+15y^{2}+4y=0\\\\ay^{2}-7y^{2}+15y^{2}=0\\\\ay^{2}+8y^{2}=0\\ \\a=-8$

If you apply the changes below to the exponential parent function f(x)=2^x, what is the equation of the new function? Shifts fiv

luda_lava [24]

the equation of the new function is:

$g(x) = 2^{x - 5} - 7$

<h3>What is the equation of the new function?</h3>

We have a function:

$f(x) = 2^x$

And we want to shift it five units to the right, and seven units down, then the new function will be:

$g(x) = f(x - 5) - 7$

If we now replace f(x), we get:

$g(x) = 2^{x - 5} - 7$

That is the equation of the new function.
