Graph the following function on the axes provided.
vitfil [10]

Step-by-step explanation:

step 1. graph f(x) = 2x + 6

step 2. y = mx + b. (slope intercept form)

step 3. b = 6 which is the y intercept so put a dot on (0, 6) or on the y axis at 6

step 4. m = 2 so put another dot up 2 and over to the right 1 from the y intercept

step 5. draw a line through your 2 points and you are done.

A sum of money is invested at 12% compounded quarterly. About how long will it take for the amount of money to double?
iVinArrow [24]
I'll use my own formula (similar to yours tho)

A=P(1+ \frac{r}{n})^{nt}
A=future amount
p=invested
r=rate in decimal
n=number of times per year compounded
t=time in years


so
when will A=2P
subsitute 2P for A
also quarterly means 4 times a year or n=4
and 12%=0.12=r
so

2P=P(1+ \frac{0.12}{4})^{(4*t)}
divide both sides by P
2=(1+ \frac{0.12}{4})^{(4*t)}
simplify
2=(1+ 0.03)^{4t}
2=(1.03)^{4t}
take the ln of both sides
ln(2)=ln(1.03)^{4t}
ln(2)=4tln(1.03)
ln(2)=t(4ln(1.03))
divide both sides by 4ln(1.03)
\frac{ln(2)}{4ln(1.03)}=t
use calculator
5.86244=t

Given the function f(x)=-2x^2+4x-7, find f(-4)
jeka57 [31]
Let's begin by evaluating f(x) using the value of 3:    f(x) = 2x2 - 4x - 4 (original function)    f(3) = 2(3)2 - 4(3) - 4 (plugging in 3 for x)    f(3) = 2 (computed result) Now let's evaluate g(x) using the value of 3:    g(x) = 4x - 7 (original function)    g(x) = 4(3) - 7 (plugging in 3 for x)    g(x) = 5 (computed result) Finally, we'll sum our results:    (f + g)(3) = 2 + 3 (add f(3) and g(3))    <span>(f + g)(3) = 5 (final answer)</span>
