sub 2 for x
f(2)=2(2)^3-3(2)^2+7
f(2)=2(8)-3(4)+7
f(2)=16-12+7
f(2)=11
Answer: 2x(5x+4x-3)
10x squared + 8x squared -6x
Step-by-step explanation:
Given
f(x) = 2x
f(3) = 2 * 3 = 6
Hope it will help):)
Answer:
4n-1
Step-by-step explanation:
Diffrence bweetween each number, 3 and -1, -1 and -5, -5 and -9 is 4
4n
find the closest numbers
4*1=4
4*0=0
4*-1=-4
4*-2=-8
now we figure out how to make these numbers into our terms of this sequence
4n-1
4*1-1=3
4*0-1=-1
4*-1-1=-3
4*-2-1=-9
so the nth term is 4n-1
Okay, so try dividing a2 from a1 (to find geometric ratio, divide a2 from a1 :) )
12 ÷ 3 = 4
See if the other numbers have the same geometric ratio.
48 ÷ 12 = 4
192 ÷ 48 = 4
The common ratio is 4.
