Answer:

f(-3) = 44

Explanation:

f(x) = 2x² - 5x + 11

Substitute the value.

f(-3) = 2(-3)² - 5(-3) + 11

Raise -3 to the power of 2.

f(-3) = 2(9) - 5(-3) + 11

Multiply 2 and 9.

f(-3) = 18 - 5(-3) + 11

Multiply -5 and -3.

f(-3) = 18 + 15 + 11

Add 18 and 15.

f(-3) = 33 + 11

Add 33 and 11.

f(-3) = 44
