Answer:
Step-by-step explanation:
f(x) =2x - 7
f( - 3) = 2( - 3) - 7 = - 13
f(3) = 2(3) - 7 = - 1
f(a) = 2a - 7
- f(a) = - (2a - 7) = 7 - 2a
f(a + h) = 2(a + h) - 7 = 2a + 2h - 7

Answer:
The positive integer is 9
Step-by-step explanation:
6 times a number is 27 less than the square of that number.
Let the number be x
These interpreted means 6 nultiplies by x is 27 less than the square of that number(x^2). F
6x= 27<x^2
0 = 27<-6x+x^2
Look for 2 numbers whose product is 27 and sum is -6
0 = 27<-9x+3x+x^2
0 = -9(3+x)+x(3+x)
0 = (x-9)(3+x)
x-9 = 0 3 + x =0
x= 9 -3 = x
The positive integer is 9
