Answer:
b) 4/52
Step-by-step explanation:
Since there are only 4 playing cards in a full deck that are labeled '2', and there are 52 cards in total - then there is a 4 out of 52 chance that a '2' card will be selected!
Answer:
Domain: - ∞ < x < ∞
Range: y > 0
Asymptote: y = 0
y-intercept: 1
Step-by-step explanation:
The <u>DOMAIN</u> is the set of possible input values, so in this case it is the set of possible x values. For this function the set of input values is not restricted, so this is why we say that the domain can be ANY value by denoting it as - ∞ < x < ∞. Another way of stating this would be to say
x ∈ R, which means x belongs to the set of real numbers. Real numbers are any number (positive, negative, zero, irrational, rational, whole etc.) except imaginary numbers.
The <u>RANGE</u> is the set of values the function takes, i.e. the output. As this function is an exponential function, the function is always positive. Hence the range is y > 0 or f(x) > 0.
An <u>ASYMPTOTE</u> is a line that the curve approaches, as it heads towards infinity (or negative infinity). Asymptotes can be horizontal, vertical or oblique. For this function, there is a horizontal asymptote at y = 0: this is because as x tends to negative infinity, the curve approaches (tends to) zero (but never actually gets there).
The <u>y-intercept</u> is the y-coordinate of the point where the curve crosses the y-axis, i.e. when x = 0. If you input x = 0 into the function y = 5^x you get y = 1. Therefore, the y-intercept of y = 5^x is y = 1
