Answer 1

u can differenciate it................

Answer 2

What is one way?

Answer 4

I need to find the intercepts if i put it on a graph

Answer 5

put x=0 and solve for y to get y-intercept and similar for x

Answer 6

Ok, thanks

Answer 7

let
y=f(x)
y=45-3x
put y=0 to find x-intercept
0=45-3x
3x=45
x=15
now put x=0 to find t-intercept
y=45-3(0)
y=45
