if f (x) = 2x² 5 , what is f (-2)
Answer:
So, the value of f(-2) is 13.
Step-by-step explanation:
The function f(x) = 2x² + 5 is a quadratic function. Its graph is a parabola that opens upward. The function's domain is all real numbers, and its range is all real numbers greater than or equal to 5.
To find the value of f(-2), we plug -2 in for x in the equation and solve:
f(-2) = 2(-2)² + 5
f(-2) = 2(4) + 5
f(-2) = 8 + 5
f(-2) = 13
So, the value of f(-2) is 13.PA BRAINLY PO LODS
