X= -2
Y= -1
Z= 1
You may use solve this problem by substituting the values as well. If everything goes wrong , go for Cramer’s rule
I would say answer number 2
An exponential function can be expressed as:
y=ab^x we have two points so we can solve
64/8=(ab^4)/(ab^1)
8=b^3
2=b, now we have:
y=a(2^x), using point (4,64)
64=a(2^4)
64=16a
4=a so
y=4(2^x)
Thé correct answer is the third one
Answer: B.54 Square inches
Step-by-step explanation: Surface Area
= 2(lb + bh + lh)
= 2(6 x 3 + 3 x 1 + 6 x 1)
= 2(18 + 3 + 6)
= 2(27)
= 54 square inches
