Answer:
I"m not sure if you wrote it the write way, but the answer is probably C
Step-by-step explanation:
log(a)+log(b)=log(ab)
This can be proven when you look at what a logarithm is.
Answer:
f(-3) = -3
Step-by-step explanation:
Step 1: f(x) means "f of x" and f(-3) means "f of -3", so you have to replace all the "x" letters in the function with the value -3.
Step 2: Apply the exponents. <em>Make sure you remember to put in the -3 and not just 3.</em>
Step 3: Use BEDMAS rules to complete the calculation.
Therefore the answer is f(-3) = -3.
There are 52 weeks in a year ,so each week you put away $20 every week.It will take 100 weeks to reach $2,000.
2x - 3 = 60
(Add 3 to both sides)
2x - 3 + 3 = 60 + 3
2x = 63
(Divide by 2)
2x / 2 = 63 / 2
x = 31.5
Answer:
This is frankly impossible.
Step-by-step explanation:
What you have given me are three x-intercepts. And it is impossible for a quadratic function to have more than two roots. However, if this was an cubic function, we could multiply (x+5)(x-1)(x-4) which results in the equation which simplifies into x^3 -21x + 20. However, this is a cubic function, not a quadratic function, so something must be wrong with this problem all together.
