Answer:
a) 2 b) 1 c) 7/6
Function a(x) = 2x + 3 has the greatest rate of change
Step-by-step explanation:
a(x) = 2x + 3
2(-1) + 3 = 1 (-1,1)
2(2) + 3 = 7 (2,7)
= 6/3
=2
b(x) = x^2 - 1
(-1)^2 - 1 = 0 (-1, 0)
(2)^2 - 1 = 3 (2,3)
= 3/3
=1
c(x) = 2^x + 1
2^(-1) + 1 = 1.5 (-1, 1.5)
2^(2) + 1 = 5 (2,5)
= 3.5/3 or 7/6
=7/6
Answer:
(0.4,1)
Step-by-step explanation:
I hope that this is for homework and not a quiz or test.
Since we already know the value of y which is 1, we can substitute it into the equation above it.
-5x+3=1
-5x=-2
x=2/5=0.4
So in (x,y) format (0.4,1)
