Answer:
Average rate of change is -1.25
Step-by-step explanation:
Answer:
-2
Step-by-step explanation:
Substitute -8 in place of x and you get (-8+2)/3 or -6/3 which is -2
Answer:
7.) 7
10.) 0
Step-by-step explanation:
When it means "evaluate the function", it's in essence asking us to see what the function spits out when we feed it a certain input. Our inputs are our x values, which spit out a y value.
Evaluating the function when x = 1:
Let's look at where the function has an x value of 1. We see it near the bottom of the table and see the y value associated with the input is 7. So when the function is fed 1 as an input, it spits out 7.
Evaluating the function when f(x) = - 2:
This one is a weird because of the new notation. Just think of it as some value of f, which we don't know (so we represent it as an x-variable) must equal -2. So let's look at our table to find out where our output is -2. We find that when f(x) = -2 the input is 0. So the input which gives -2 is 0.
Answer:
3x^5 -2x^4 -x^2 +x -21
Step-by-step explanation:
We need to subtract g(x) from f(x)
f(x) = 3x^5 +6x^2 -5
g(x) = 2x^4 +7x^2 -x+16
f(x) -g(x) = 3x^5 +6x^2 -5 - (2x^4 +7x^2 -x+16)
Distribute the minus sign
3x^5 +6x^2 -5 - 2x^4 -7x^2 +x-16
I like to line them up vertically
3x^5 +6x^2 -5
- 2x^4 -7x^2 +x-16
---------------------------------------
3x^5 -2x^4 -x^2 +x -21
I think -3 but I’m kinda dumb so idk
