to work it out just go output f (x) - input x so, 3 - 1 = 2 and double check this using your next equations 4 - 2 = 2
Make an equation.
80% = 0.8
'of' is multiplication
'what number' is 'x'
'is' is an equal sign
0.8 * x = 64
0.8x = 64
Divide 0.8 to both sides:
x = 80
Answer: -1/3
Step-by-step explanation:
The formula is y2 - y1/ x2 - x1 . So the answer would be -1/3 bc 3 - 2 = 1 and -11 - (-8) = -3.
Answer:
7) Obtuse, I didn't use a protractor, so I'm estimating about 130 degrees.
8) Straight, all straight lines are equal to 180 degrees.
9) Acute, I estimated about 30-40 degrees, again, no protractor used.
Step-by-step explanation:
Answer:
f(x)= 4x+9
F(x)=1/x
Step-by-step explanation:
An odd function accomplish the following condition:
f(-x) = -f(x) (1)
By checking (1) on each of the next functions, we have:
f(-x) = (-x)^3 - (-x)^2 
-f(x) = - (x^3- x^2)
f(-x) = (-x)^5 -3(-x)^3 + 2(-x) -f(x) = -x^5 +3x^3 +2x
f(-x)= -4x +9 = -f(x)
F(-x) = -1/x =-F(x)
