Question

solve for x at f(x) = -5 given the function below. put your answer in function notation. f(x) = (-10 + x)/8

Explanation:

Step1: Igualar la función a -5

$$\frac{-10 + x}{8} = -5$$

Step2: Multiplicar por 8 ambos lados

$$-10 + x = -5 \times 8$$
$$-10 + x = -40$$

Step3: Despejar x sumando 10

$$x = -40 + 10$$
$$x = -30$$

Step4: Escribir en notación funcional

$$f(-30) = -5$$

Answer:

$f(-30) = -5$
