  • The value for f(0) is -7
  • The value of x for which f(x) = 0 is 3.5
  • The answer in part a shows that the y-intercept of graph f(x) is at (0, -7) while part (b) shows  that the x-intercept of the graph f(x) is at (3.5, 0)

Given the function f(x) = 2x - 7

a) To compute f(0), we will simply substitute x = 0 into the given expression as shown;

f(0) = 2(0) - 7

f(0) = 0 - 7

f(0) = -7

Hence the value for f(0) is -7

b) For f(x) = 0

Substitute f(x) = 0 in the expression as shown;

0 = 2x - 7

-2x = -7

x = 7/2

x = 3.5

Hence the value of x for which f(x) = 0 is 3.5

c) The answer in part a shows that the y-intercept of graph f(x) is at (0, -7) while part (b) shows  that the x-intercept of the graph f(x) is at (3.5, 0)

Please help me!!! :(
PSYCHO15rus [73]

Answer:

15.75x^{10}y^{19}

Step-by-step explanation:

To find the 5th term in the expansion, we first will need to apply the binomial theorem. I have attached an image of the binomial theorem formula due to not being able to type it.

After applying the binomial theorem and simplifying, you should get:

512x^{18}y^{27}-576x^{16}y^{25}+288x^{14}y^{23}-84x^{12}y^{21}+\frac{63x^{10}y^{19}}{4}-\frac{63x^8y^{17}}{32}+\frac{21x^6y^{15}}{128}-\frac{9x^4y^{13}}{1024}+\frac{9x^2y^{11}}{32768}-\frac{y^9}{262144}

Our 5th term here is: \frac{63x^{10}y^{19}}{4} which is equal to 15.75x^{10}y^{19}

~Hope this helps! Sorry if my answer is confusing at all, it's pretty difficult to explain.~

I will answer second attachment and after since I can't see the firs attachment



2nd attachment

if x is negative, then the first number gets infinitely small
look at the second number, the first 2 is -2 which is wrong since it should be +2
3rd option is not because if x=-2, then y=1
answer is D


3rd attachment
2nd: f(x)=60*1.15^x
3rd: no xint
6th: after 7.86 years value tripples
7th maybe: after 8 years value is 183.51, not exatly 184.00


4th attachment
nth score is
f(n)=57+4(n-1)
9th is
f(9)=57+4(9-1)
57+32=89
answer is C 89


5th
f(t)=23000(1.02)^t
t=time in years from 23000
