Answer:

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

Step-by-step explanation:

y = $kb^{x}$

Use (0, -3) to find k

$-3 = kb^{0} = k(1) = k\\$

So, k = -3

Now use (4, -48) to find b

-48 = $-3b^{4}$

$b^{4}$ = 16

b = 2

Since k = -3 and b = 2, $y = -3(2^{x})$

Try this option:
A. f(4)=7 - false; explanation: x=4, it means that x>0 and x²-1=4²-1=15 ⇒ f(4)=15.
B. f(1)=0 - true; explanation: x=1, it means that x>0 and x²-1=1-1=0.
C. f(-1)=2 - true; explanation: x=-1, it means that x<0 and -x+1=1+1=2.
D. f(-2)=0 - false; explanation: x=-2, it means that x<0 and -x+1=2+1=3 ⇒ f(-2)=3.
