1. Find the slope of the graph of the linear function f with f(0)=4 and f(3)=13.

I have no idea how to do this.. :(
__________________________________

Evaluate the function when x=3, x=0, and x= -2.

2. f(x)=-1/2x+3

3. h(x)=5.5x+4
my anwers: 20.4, 4, 7

4. g(x)=1/8-4

5. k(x)=14-4x

Please check if numbers 2-5 are correct. Thanks.

• Algebra -

on the first.

slope= (f(3)-f(0))/(3-0)

the others are correct, but I would have done 4 in fractions.

Thanks a lot!! =))

KukuMonkey, double check you work when you work with negative numbers.

2.
f(x)=-1/2x+3
f(-2)=4

3. h(x)=5.5x+4
my anwers: 20.4, 4, 7
h(3)=20.5
h(0)=4 (OK)
h(-2)=-7
