There is no restriction upon the domain, the x values, and is all real numbers or (-oo,+oo)
From such it is clear that the domain also contains all real numbers.
The range of f(x) is (-oo,+oo)
Answer:
$42 - 19 = 23 - 15 = $8
Step-by-step explanation:
Answer:
<u>x</u>
Step-by-step explanation:
Let's simplify the LHS so it can be equated to the RHS.
Hence, the missing term in the numerator of the answer is <u>x</u>
Step-by-step explanation:
Yes, the degree of the of the polynomial will tell how much roots it has.
A linear equation with degree has one root so it only has 1 possible answer.
A quadratic equation with the degree of 2 has two possible roots.
So write a polynomial equationcwith the highest degree of 9.
Answer:
factorisation method
4x² - 3x + 9 = 2x + 1
4x² - 3x-2x +9-1 = 0
4x² - 5x + 8 = 0
sum = -5
product= 4x8
32
factors=(try to look for the numbers when added they give -5 a!d when multiplied they give 32
press the numbers in the position of -5
factorise
each blacket equal it to 0
and solve for the two values of x
