F(x) = 4x + 8
Find x in terms of f(x):-
4x = f(x) - 8
x = (f(x) - 8 ) / 4
replace x by h(x) and f(x) by x
h(x) = (x - 8 ) /4
I cant get any of the choices
Answer:
<h3>0.2</h3>
Step-by-step explanation:
Given a linear function f(x) that varies at a constant rate of change 1.5 with respect to x, If x varies from x = 1.3 to x = 1.5, the to get the amount by which x change by, we will use the expression;
Δx = x₂-x₁
x₂ is the final value of x
x₁ is the initial value of x
Given x₁ = 1.3 and x₂ = 1.5
Substitute the values in the formula above;
Δx = x₂-x₁
Δx = 1.5 - 1.3
Δx = 0.2
Hence the value of x change by 0.2
