So you’re basically going to move all the point the number of unit so if we look at the first one all your point will just move to the left one square. That’s all I know for 1-4 and for the other 2 plot the shapes with the original numbers and then move the units. So you just move the points over however many units ajd then you just have the same shape but in a different position and for the next page you’re going to be the one making the rules so like for number 11 the rule will be 4 units up

Evaluate f(x) = 2|x – 5| for f(–5) and f(0).

Elanso [62]

Answer:

f(–5) = 20, f(0) = 10

Step-by-step explanation:

f(-5):

f(-5) = 2|-5 -5|

f(-5) = 2|-10|

f(-5) = 2(10)

f(-5) = 20

f(0):

f(0) = 2|0 - 5|

f(0) = 2|-5|

f(0) = 2(5)

f(0) = 10

Is x^2-1 a polynomial

77julia77 [94]

Answer:

Yes it's a binomial.

Step-by-step explanation:

A polynomial is an expression with more than one term that often has variables and exponents on the variable. Since this has two terms separated by a subtraction sign with one term being a variable to the exponent of 2 then this is a polynomial. It is called a binomial. More than 2 terms are referred exclusively as a polynomial with ___ terms.
