What are the x- intercepts of the function f(x)= -2x-3+20?
1 answer:
Answer:
x = .464
Step-by-step explanation:
Assumptions: Equation is . Thus having an asymptote at the value x=0.
- To solve for the x-intercepts, we plug in 0 for f(x).
- We can subtract 20 from both sides, leaving us with
- We can divide both sides by -2.
.
- Now we multiply both sides by x^3, to get rid of the denominator on the right-hand side.
.
- We now divide both sides by 10 and take the cube root. Leaving us with x =
or .464. (One x-intercept.)

<u>Sample Space</u>
The sample space of a random experience is a set of all the possible outcomes of that experience. It's usually denoted by the letter .
We have a number cube with all faces labeled from 1 to 6. That cube is to be rolled once. The visible number shown in the cube is recorded as the outcome. The possible outcomes are listed as the sample space below:
Now we are required to give the outcomes for the event of rolling a number less than 5. Let's call A to such event. The set of possible outcomes for A has all the numbers from 1 to 4 as follows
