Idont understand anything about my math !
the function g(x) is a shift of the function f(x) = 7x. using the table, choose the correct expression for g(x).
x / g(x)

0 / -7
1 / 0
2 / 7
3 / 14
4 / 21
(the slashes are spaces since i cant put a table on here and it puts them together without them)
a. f(x) + 1
b. f(x - 1)
c. f(x + 1)
d. f(x) - 1

Write a polynomial function f of least degree that has rational coefficients, a leading coefficient of 1, and the given zeros. 3, 4+2i, 1+(sqrt)7 the answer is supposed to be: f(x)=x(^5)-13x(^4)+60x(^3)-82x(^2)-144x+360 what am i doing wrong?

The annual snowfall in a town has a mean of 38 inches and a standard deviation of 10 inches. last year there were 63 inches of snow. find the number of standard deviations from the mean that is, rounded to two decimal places. 0.44 standard deviations below the mean 2.50 standard deviations below the mean 0.44 standard deviations above the mean 2.50 standard deviations above the mean

Pls the last one and it has to be like number 6
