Given f(x)=-x^(2)+5x-6, find f(-9) Answer:

Substitute x with -9: Given the function f(x) = -x^2 + 5x - 6, we need to find the value of f(-9). To do this, we will substitute x with -9 in the function and simplify. f(-9) = -(-9)^2 + 5(-9) - 6Calculate (-9)^2: First, we calculate (-9)^2, which is the square of -9. (-9)^2 = 81Multiply 5 by -9: Next, we multiply 5 by -9. 5(-9) = -45Substitute values and simplify: Now, we substitute these values into the function and simplify. f(-9) = -(81) + (-45) - 6Perform arithmetic operations: We simplify the expression by performing the arithmetic operations. f(-9) = -81 - 45 - 6Final value: Adding the numbers together, we get the final value. f(-9) = -81 - 45 - 6 = -132

Q. Given

f(x)=-x^{2}+5 x-6

, find

f(-9)

\newline

Answer:

Substitute $x$ with $-9$ : Given the function $f(x) = -x^2 + 5x - 6$ , we need to find the value of $f(-9)$ . To do this, we will substitute $x$ with $-9$ in the function and simplify. $\newline$ $f(-9) = -(-9)^2 + 5(-9) - 6$
Calculate $(-9)^2$ : First, we calculate $(-9)^2$ , which is the square of $-9$ . $(-9)^2 = 81$
Multiply $5$ by $-9$ : Next, we multiply $5$ by $-9$ . $5(-9) = -45$
Substitute values and simplify: Now, we substitute these values into the function and simplify. $\newline$ $f(-9) = -(81) + (-45) - 6$
Perform arithmetic operations: We simplify the expression by performing the arithmetic operations. $f(-9) = -81 - 45 - 6$
Final value: Adding the numbers together, we get the final value. $\newline$ $f(-9) = -81 - 45 - 6 = -132$
