Question

Using your function, F(3)=2(3) + 5 explain to the Martians how to solve for f(3). Show your work and explain each step using complete sentences.

Answer 1

desperate help :(

Answer 2

you have a function y=f(x).

f(x) = 2*x + 5

Want f(x) , when x=3
f(3) = 2*3 + 5
= 11

Answer 3

Ok i figured

Answer 4

Thank you so much

Answer 5

Using complete sentences, describe to the Martians how to find the inverse of your function @danjs

Answer 6

to find an inverse you will change the subject of the function to the independent variable, x. After this, you swap x and y.

Answer 7

Cn you show me an example?

Answer 8

Change the subject to x:
y = 12x - 5
12x = y + 5
x = (y+5)/12

Swap x and y
y = (x+5)/12
So your inverse of y = 12x - 5 is y = (x+5)/12
