Answer:
Step-by-step explanation:
1. when x is 1 f(x) = 5, as it goes down we notice an addition of 4 corresponds to the value of f(x)
thus the function f(x) = x+4
2. when x=0 f(x) = 0
when x=3 f(x) = 9
meaning for every value of x, the function f(x) is the square of x (x²)
3. if x = 0 y =0
if x= 3 y =7 the value of y depends on the square of x minus , x= 3 y = 3²-2 = 9-2=7
if x=6 y= 34 proving it when x=6, y= 6²-2 = 36-2= 34
therefore the value of y = x²-2
4. when x = 2, f(x) = 7, validating the formula f(x)=2x+3, if its true or not
2(2)+3 = 4+3 = 7
when x = 10, f(x) = 23, validating the formula f(x)=2x+3, if its true or not
2(10)+3 = 20+3 = 23
therefore these proves the formula right
5. when x = 3, f(x) = 11, validating the formula f(x)=5x+4, if its true or not
5(3)-4 = 15-4 = 11
when x = 7, f(x) =31, validating the formula f(x)=5x+4, if its true or not
5(7)-4 = 35-4 = 31
6. when x = 0, f(x) = 1, validating the formula f(x)=2x+1, if its true or not
2(0)+1 = 0+1 = 1
