Solve y = f (x) for x. Then find the input when the output is -3.
f(x) = 3x+5


Sagot :

Answer:

f(-3)= -4

Step-by-step explanation:

Given function in the question is,

f(x) = 3x + 5

Here, values of 'x' are the input values of the function.

And the values of the function f(x) by substituting the values of 'x' are the output values.

If the output value of the function 'f' is -3,

-3 = 3x + 5

3x = -3 - 5

x = [tex]-\frac{8}{3}[/tex]

Therefore, for the input value x = [tex]-\frac{8}{3}[/tex], output value of the function will be f(x) = -3.
