Question

Please help im desperate if f(x) = 5 + 3x find the value of the dependent variable if the if he independent variable is -4 and if you know hoew to do this pls answer my other question

Answer 1

Answer: the dependent variable is -7

Explanation:

this is really simple all we have to do is plug -4 instead of x

so the equation is going to be f(-4)=5+3(-4)

now we just solve like normal so that would be...

f(-4)= 5+ -12 (3*-4 is -12)

f(-4)= -7

i hope it helps

Answer 2

[see below]

Explanation:

The dependent variable is considered 'y' or 'f(x)'.

The independent variable is considered 'x'.

`f(x)=5+3x\\\\f(-4)=5+3(-4)\\\\f(-4)=5-12\\\\\boxed{f(-4)=-7}`

Hope this helps.
