Evaluate f(x) = -x squared +1 for x = -3

f(x) = -8  when  x= 3

Step-by-step explanation:

Given f(x) = -x² + 1

It is required to find f(x) when x = 3

So, we need to substitute with x =3 at the function f(x)

at x = 3

f(x) = - 3² + 1 = - 9 + 1 = -8

So, at x = 3 ⇒ f(x) = -8

see the attached figure.

choice b is correct

step-by-step explanation:

we have been given the following system of inequalities;

we are required to graph the solution to the system of inequalities. using a graphing tool, the graph of the system is as shown in the attachment. the continuous line represents the graph of while the dotted line represents .

the answer for this question is : 360°

step-by-step explanation:

we have been given a triangle   we need to tell which one of these is a triangle below to map onto itself.

360° rotation is the complete rotation which eventually leads to the same figure which is given.

the correct will be, that is 360° that will cause the triangle below to map onto itself.
