The last two choices are appropriate.
Both give you f(1) = 7, f(2) = 9.50, f(3) = 12.00, ... as they should.
I need the picture to answer it
You can only add x terms together only if they have the same exponent. For example you can add 2x^2 and x^2 but you cannot add x^2 and x^3.
In this particular problem, you can add 4x^4 and x^4, and x and 8x. So,
<span>
(x + 4x^4) + (x^4 - 2 + 8x)
</span>= 5x^4 + 9x -2
Answer:
x=3.5
Step-by-step explanation:
12x=4(x+2)+20
multiply the parentheses by 4
12x = 4x+8 +20
add 20 to 8
12x = 4x +28
subtract 4x on both sides
8x = 28
divide both sides by 8
x=3.5
Answer:
1) f is the name of the function
2) x is the argument
3) output is (3x + 1)
Step-by-step explanation:
In function notation, The expression "f (x)" simply means that f is a formula that has an input variable known as "x". It should be noted that f(x) does not imply that we multiply f and x. Hence, f is the name of the function.
Now, the term "x" is an input variable known as the argument of the function.
f(x) is the output of the function and is; 3x + 1
