what is the output value of the given function when the input value is 9?\ny = -5x - 2\n(9, ?)

Explanation:

Step1: Substitute input value into function

Substitute (x = 9) into (y=-5x - 2). So, (y=-5\times9 - 2).

Step2: Calculate multiplication part

Calculate (-5\times9). (-5\times9=-45). Then (y=-45 - 2).

Step3: Calculate subtraction part

Calculate (-45-2). (y=-47).

Answer:

(-47)
