Answer:
Step-by-step explanation:
B = 2/5(A - 9)
(5/2)B = A - 9
A = 9 + (5/2)B
The answer is either B, and you forgot to put in the ^2 in the answer choice, or C, and you forgot to put an x where there is a _ in the question.
Check the actual question (the one you recieved, not the one posted here) and see where the mistakes are. If f(x) = 8x - 4x - x^3, then your answer is C. However, if B is actually -x^3 + x^2 + 3x - 1, then the answer is B.
Answer:
Let's calculate:
22-5
• Remove minus in the exponent and invert the base:
= (1/22)5
• Expand the multiplication:
= (1/22) * (1/22) * (1/22) * (1/22) * (1/22)
• Find your result:
= 1/5153632 ≈ 0.000000194038
90/2 = 45 degrees twices
These both are 45 degrees which is less than 90
Answer:
Only option C shows a function
Step-by-step explanation:
The vertical line test is a visual way to determine if a curve is a graph of a function or not. A function can only have one output, y, for each unique input, x. This means that a vertical line made in the domain of the function can crosses the curve of the function only once. If it crosses the curve of the function more than once, then the curve is not a function.
In option A, a vertical line would cross two values, so it is not a function.
The curve of option B is a vertical line itself, so a vertical line would intersect an infinite amount of points; then it is not a function.
Option C is a function because a vertical line would only intersect the function's curve (which is a line) once.
