Answer :
The function f(x) = 3x^2 + 4x - 5 represents a quadratic function. To find the value of f(-2), we substitute -2 into the equation and perform the necessary calculations. The resulting value is -1.
We are given the function f(x) = 3x^2 + 4x - 5, and we need to evaluate f(-2), which means finding the value of the function when x is equal to -2. To do this, we substitute -2 into the equation:
f(-2) = 3(-2)^2 + 4(-2) - 5
= 3(4) - 8 - 5
= 12 - 8 - 5
= -1
By simplifying the expression, we find that f(-2) equals -1.
In conclusion, when we substitute -2 into the equation f(x) = 3x^2 + 4x - 5, we get a value of -1 for f(-2).
