Solve the following inequalities graphically on the set of axes below state the coordinates of a point in the solution set
kakasveta [241]

Answer:

A solution point is (2,2)

Step-by-step explanation:

Graph the lines. If it is just greater that or less than, use dashed lines. I fits greater than or equal too, or other symbols like that, use a solid line

Use the test point (0,0). If it satisfies the inequality, shade the side of the graph with that point (you can use any test point, not just (0,0)). If it doesn't satisfy, then shade the other side

The Shaded area shared by both lines is the area of the solution

Evaluate f(x) = –x2 + 1 for x = –3. –9 4 –4 –8
Klio2033 [76]

Answer:

-63

Step-by-step explanation:

Write the problem as a mathematical expression.

f(x)=-x^2+1  for x =3-9 4-4-8

Simplify  4−4−8  to substitute in f(x)=−x^2+1

Subtract  4  from 4

0-8

Subtract  8  from 0

-8

Replace the variable  x  with  −

8  in the expression

f(-8)=-(-8)^2+1

Simplify

f(-8)=-64+1

f(-8)=-63

Answer = -63
