Given the function f(x)= 5(x+4) -6 solve for the inverse function when x = 19

1 is the answer.

Step-by-step explanation:

Given is a function as

is given

Solve for x in terms of f(x) to get inverse

Replace x by f inverse and f(x) by x to get inverse

This would be the inverse of x.

Now substitute x=19, to find f inverse of 19

Hence answer is 1.

it is contrapositive

i could not see the question too well so check yourself again too . this is because i want you to get it correct.

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.
