Wouldn't this be science because it's dealing with temperature?
32. given (0,3)
fond slope by formula y2-y1/x2-x1 with any two points in the table ( you are lucky to be able to use formula in this equation!!) 5.3-3/1-0
2.3/1= 2.3 is slope you are able to check if this is true by doing it with every (x,y) point they give you.. luckyly the slope holds true for all the equation is
y=2.3x+3
33. this one the way I did it was plugging in (x,y) onto each equation and see of any hold true
y=4x+2.1
y=4x^2+2.1
y=2.1×4^x
y=4x
Let's plug in (1,8.4)
8.4=4 (1)+2.1
8.4=4+2.1
8.4=6.1 not true
8.4=4 (1)^2+2.1
8.4=4+2.1
8.4=6.1 not true
8.4=2.1×4^1 (1)
8.4=2.1×4
8.4=8.4 TRUE
8.4=4 (1)
8.4=4 not true
Answer: the answer is
Step-by-step explanation:
put g of x in f of x
(2x)^2 - 1
=4x^2 - 1
Answer:
g(x) , f(x) , h(x)
Step-by-step explanation:
I think your question is missed of key information, allow me to add in and hope it will fit the original one.
Please have a look at the attached photo.
My answer:
As we all know, the average of change can be determined by the following formula:
As can be seen in the attached photo, The function f(x) is given by:
x = -1 we have:
= 2
x = 3 we have:
= 34
Hence,the average rate of change of f(x) is:
As can be seen in the attached photo, The function g(x) is a straight line that passes through: (-1,-2) and (3,0)
<=> when x = -1 y = -2 and when x = 3 y = 0
=> the average rate of change of g(x) is:
Based on the table of values of h(x) we have:
h(-1)= 14
h(3)= 62
=> the average rate of change of h(x) is:
Therefore, the correct order of the functions from least to greatest according to the average rate of change is: g(x) , f(x) , h(x)
Hope it will find you well.
