Math Problem Statement

if f(x)=4x-7 and g(x)=-3x+5 find each value

Solution

Sure! To solve for the values of the functions f(x)=4x7f(x) = 4x - 7 and g(x)=3x+5g(x) = -3x + 5, you need to evaluate the functions at specific values of xx. However, since you didn't provide specific values for xx, I'll assume you want the general form for the expressions.

General Expressions:

  1. For f(x)f(x): f(x)=4x7f(x) = 4x - 7
  2. For g(x)g(x): g(x)=3x+5g(x) = -3x + 5

Example Calculations:

If you wanted to find specific values, you would plug in a given value of xx into each function.

For example, if x=2x = 2:

  1. f(2)f(2): f(2)=4(2)7=87=1f(2) = 4(2) - 7 = 8 - 7 = 1

  2. g(2)g(2): g(2)=3(2)+5=6+5=1g(2) = -3(2) + 5 = -6 + 5 = -1

If you have specific values of xx you want to evaluate, let me know!

Would you like to see more details or have any questions?

Relative Questions:

  1. What is the value of f(x)f(x) when x=1x = -1?
  2. What is the value of g(x)g(x) when x=0x = 0?
  3. How do you find f(3)+g(3)f(3) + g(3)?
  4. What happens to f(x)f(x) as xx increases?
  5. Can you determine the intersection point of the graphs of f(x)f(x) and g(x)g(x)?

Tip:

When solving function problems, always check if you need to substitute a specific value for xx or if you need to manipulate the functions algebraically first.
