Suppose f is a linear function and f(x) varies at a constant rate of change of 1.5 with respect to x. Suppose we know that f(1.7)=2.5.Suppose xvaries from x=1.7 to x=1.9...How much did xchange by?

The exchange by 0.2.

Given that,

Based on the above information, the calculation is as follows:

 = x final - x initial

  = 1.9-1.7

= 0.2

Therefore we can conclude that the exchange by 0.2.

0.2

Step-by-step explanation:

The amount that x changed by is expressed as;

∆x = x final - x initial

∆x = xf - xi

If x varies from x=1.7 to x=1.9, then;

x final = 1.9

x initial = 1.7

Substitute into the expression above

∆x = 1.9-1.7

∆x = 0.2

Hence the variable x changed by 0.2

is means division by fractions
