Which of the following is true for the function /(x) = x - 3? a. f(x) is increasing between 0 and 5 and has an x-intercept at x = 3. b. f(x) is decreasing between 0 and 5 and has an x-intercept at x = 3. C. f(x) is decreasing between 0 and 5 and has an x-intercept at x = -3. d. f(x) is increasing between 0 and 5 and has an x-intercept at x = -3.​

is this further maths?

Step-by-step explanation:

Could you explain what the question means into an equation?

problem:

f(x) = - 2/3x + 5; f(5/2)

substitute 5/2 in for x:

f(5/2) = -2/3(5/2) + 5

simplify the right side:

f(5/2) = -5/3 + 5

f(5/2) = 10/3

f(5/2) = 10/3
