Show that the equation x^2 +6x -5 has a solution between x=0 and x=1

f(0)= 0^2+0-5= -5

f(1)=1+6-5= 2

Step-by-step explanation:

To do this we just plug in 0 for x and then 1

if the sign of the answer changes that must mean that the line crosses the x axis (which obviously means there's a solution)

f(0)= 0^2+0-5= -5

f(1)=1+6-5= 2

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

answer:

f(5/2) = 10/3

i hope this you!
