Suppose f(x)=2x-5 and g(x)= |-3x-1|. Find each value.
f(1)+g(2)
How would I solve this problems? If anyone could give me the step, thanks a lot.
If f(x)=4x+3
then f(6)=4(6)+3, i.e. replace x on the right hand side by the number in parentheses on the left.
Proceed the same way for f and g.
Where do you get the 6 from?
Does f(1) + g(2) mean the sum of those 2 output? Thanks
The (6) is just an example.
In your case, you'd do the same thing with 1 and 2 respectively, as you have suggested.
Yes, it's the sum of the two evaluated expressions.
To find the value of f(1), you need to substitute 1 into the function f(x) = 2x - 5. So, we have:
f(1) = 2(1) - 5
= 2 - 5
= -3
Next, to find the value of g(2), you need to substitute 2 into the function g(x) = |-3x - 1|. So, we have:
g(2) = |-3(2) - 1|
= |-6 - 1|
= |-7|
= 7
Now, you can find the sum of f(1) and g(2):
f(1) + g(2) = -3 + 7
= 4
Therefore, f(1) + g(2) equals 4.
