Is somebody able to explain to me what I’m suppose to do in very simple terms?

"f" is a set and it has a few points, "f" is also a function, or we can say that "f" is a function that we can graph with many points and each point has an x-coordinate and a y-coordinate, so each point is a (x,y) pair on the function "f".

the first argument in the pair is the value of the "independent" variable, for this case we can call it "x", and the second argument is the "dependent" variable, for this case we can call it "y".

so after all that mumble jumble, what is f(2) asking?

well, is asking, "when x = 2, what's 'y'?

hmmm let's look at the set, it has a pair of (2 , 2), meaning x = 2 and y = 2, well, there you have it f(2) = 2.

let me do "a, c and f" only.

other way to read that is the coordinates of the set "g" are (x , g(x) ), and they're a point lieing on the graph of the function g(x).

answer: c, the green line

step-by-step explanation:

there is no black line, eliminate b.

simple interest implies periodic payments, but the red line shows no payments, eliminate d.

simple interest has equal payments. if paid say every day, the graph is about a straight line (actually a stairstep).

the yellow line is not straight, eliminate a.

check: the green line is straight, answer is c.

simple interest with positive interest rate gives a straight line sloping up to the right. green line:

g(t) = $100 + ($200-$100) ÷ (20 years) × (t years)

= $100 + (4%/year) × ($100)(t years)

incidentally, the yellow line curving upward represents continuously compounded interest

y = $100 × 2^(t years / (14 assuming the yellow line hits $200 at 14 years. 2^0 is 1, so y(0) = $100; 2^(14/14) is 2, so y(14) = $200.

whole number data type

step-by-step explanation:

as whole number type represents whole number

like 1, 2 ,3, 4

in other words the whole numbers are those numbers which cannot be written infraction.

since we can take days as a whole number i.e 1 day 2 day and we cannot write 1.2 day hence we will use whole number data type
