Substitute the value of x = 3 to the equation of the function:

f(x) = 2x² - x → f(3) = 2(3²) - 3 = 2(9) - 3 = 18 - 3 = 15


Answer: f(3) = 15

iren2701 [21]

Answer:

C. one solution

Step-by-step explanation:

The number of solutions can be found from the number of intersection points.

There are 2 lines, a parabola (curve) and a horizontal line that is parallel to the x axis.

We see that there is 1 point of intersection between the 2 lines, at (2,1)-right 2 and up 1. Therefore, this non linear system has 1 solution.

C. one solution is the correct answer.
