F(x) function has a starting value of $6.00 and increases from there.So the y-intercept is 6.

g(x) function shows in the table that when x = 0, y = 6. This is the y-intercept.

h(x) shows on the graph that the y-intercept is 4.

j(x) is an exponential growth function, a * b^x where a is the y-intercept.
y = 10^ x^x has a y-intercept at 10.

The smallest y-intercept is function h(x).

What is the range of y = (x - 5)^2 – 1?

Setler79 [48]

1. The graph is a parabola.

2. The parabola opens up, because there's no negative number in front of $(x-5)^2$ .

3. The vertext is (5,-1), because of the vertex form.

This means that that -1 will be the least y-value used on the graph and the garph will open up from there.

The range is (-1, infinity) or { y | y > -1 }.

A fast-food company is interested in knowing the probability of whether a customer viewed an advertisement for their new special

lord [1]

Answer:

45% probability that a randomly selected customer saw the advertisement on the internet or on television

Step-by-step explanation:

We solve this problem building the Venn's diagram of these probabilities.

I am going to say that:

A is the probability that a customer saw the advertisement on the internet.

B is the probability that a customer saw the advertisement on television.

We have that:

$A = a + (A \cap B)$

In which a is the probability that a customer saw the advertisement on the internet but not on television and $A \cap B$ is the probability that the customers saw the advertisement in both the internet and on television.
