Answer:
f(-4) = 4
f(-1) = 0
f(-6) = -4
Step-by-step explanation:
Since functions, f(x), are interpreted as "The function of x," then it means that the values inside the parenthesis of the f(x) are the x values. Looking at the graph, the following functions are located as the curve crosses the given points on the graph:
f(-4) = 4
f(-1) = 0
f(-6) = -4
Answer:
Factor the numerator and denominator and cancel the common facotors which would give you 0.07843137

Laura DATA:
Time = x hr/job ; Rate = 1/x job/hr
Jeri DATA
Time = x+2 hr/job ; Rate = 1/(x+2) job/hr
Tammy DATA:
Time = (x+2)/2 hr/job ; Rate = 2/(x+2) job/hr.
Together DATA:
time = 4/3 hr/job ; Rate = 3/4 job/hr
EQUATION:
rate + rate + rate = together rate
1/x + 1/(x+2) + 2/(x+2) = 3/4
Multiply thru by 4x(x+2) to get:
4(x+2) + 4x + 8x = 3x(x+2)
16x + 8 = 3x^2+6x
3x^2-10x-8 = 0
3x^2-12x+2x-8 = 0
3x(x-4)+2(x-4) = 0
(x-4)(3x+2) = 0
Positive answer:
x = 4 hrs. time for Laura to do the job
x+2=6 hrs. time for Jeri to do the job
(x+2)/2 = 3 hrs. time for Tammy to do the job
I think you meant to put 3x +7. anyhow, i'll use numbers 1, 2, and 3. that would be 10, 13, and 16.
