Answer
A expression is an number or a variable and a combination of numbers in variables and operation symbols. A equation is made up of two expressions or connected by an equal sign.
Step-by-step explanation:
Part B) Passes through (−3, 2) and (1, −3)
Part C)m=2/5 and y-intercept =-6
Part D) x-Intercept = 4 and y-intercept = −2
Part E) Passes through (−2, 2) and parallel to 4x − 3y − 7 = 0
Answer:
(a) F(x) = 2x^2 - x - 1
Step-by-step explanation:
The quadratic regression function of a graphing calculator does this nicely.
The one attached shows the function to be ...
F(x) = 2x^2 -x -1
__
Additional comments
The supplied point (0, -1) tells you the y-intercept is -1. That means the constant in the function's equation will be -1. Only one answer choice has that.
F(x) = 2x^2 -x -1
__
As always, the first step in problem solving should be to look at the problem, and look at the available solution choices. Understanding these things will generally allow you to throw out answer choices that don't provide a sensible answer to the question. Here, that leaves you with only one answer choice, which is all you need.
A.
{(7, 12), (1, –5), (3, –10), (2, –5)}
B.
{(1, 2), (1, 5), (1, –1), (1, 4)}
C.
{(–3, 4), (–2, 5), (0, 9), (0, 12)}
D.
{(8, –1), (2, –1), (3, 8), (2, 5}
(1,1)
(1,0)
(-5,0)
The semicolon in math mean [1;2;3].
We are given that;
Semicolon
Now,
A semicolon in math can have different meanings depending on the context. One common use of a semicolon is to separate variables from parameters in a function definition1. For example, f(x;y) means that f is a function of the parameter y that returns a function of the variable x. Another use of a semicolon is to separate the elements of a matrix or a vector2. For example, A = [1;2;3] means that A is a column vector with three elements: 1, 2 and 3. A third use of a semicolon is to indicate a conditional probability3. For example, P(A;B) means the probability of A given B, or the probability of A occurring when B is true.
Therefore, by mean the answer will be [1;2;3].
