Answer:

f(-2) =8

Step-by-step explanation:

f(x) = 3x^2+x-2

Select all the ordered pairs that are solutions of the equation.

mafiozo [28]

Answer:

B. (-1,7)

C. (0,5)

D. (2,3)

Step-by-step explanation:

We solve this question looking at the graphic.

A. (-7, 1)

When $x = -7, y \rightarrow \infty$ , and thus (7,-1) is not solution of the equation.

B. (-1,7)

When $x = -1, y = 7$ , and thus (-1,7) is a solution of the equation.

C. (0,5)

When $x = 0, y = 5$ , and thus (0,5) is a solution of the equation.

D. (2,3)

When $x = 2, y = 3$ , and thus (2,3) is a solution of the equation.

E. (3, 2)

When $x = 3, y \neq 2$ , and thus (3,2) is not part of the solution

F. (5,0)

When $x = 5, y \neq 0$ , and thus (5,0) is not part of the solution
