Answer:
7x^2 - 2x - 3.
Step-by-step explanation:
Starts with 7x^2 then a term in x then a constant.
The graph is not a function, as it does not pass the vertical line test. The lines at 2,-1 and 2,3 overlay and pass the vertical line more than once, meaning that the graph is not a function.
Answer:
x=3
Step-by-step explanation:
x^2=9
x=3
Answer:
The y-intercept is (0,-26)
Step-by-step explanation:
Given two points P(a,b) and Q(c,d), the line that passes for both points can be found with the expression

We'll take the first two points P(34,-52) and Q(51,-65) to find

Let's verify if the third point is on the line:

It belongs to the line. To find the y-intercept of the line, we set x to 0

The y-intercept is (0,-26)
Greatest to least: 4/9, 44/100, 0.4.
