Jack must score 28 problems correct. To get a 92% he must answer 92% of the 30 questions right. which means 0.92*30=27.6, but it is not possible to score 0.6 of a problem right so you would round to 28, which guarantees Jack scores a 92 because if we round down, Jack would score less than a 92

Sets<br>The table represents a function.<br>What is f(-2)?<br>TITLE<br>TE<br>♡ ♡<br>oooo<br>HT​
jek_recluse [69]

Answer:

can you elaborate more on your question please

if this is the question or similar. An exponential function is given in the form f(x)-a*bx. If f(0)=3 and f(1)=15, what's the value of f(-2)?

this is how to solve it:

f(0) = 3 = a*b0  Therefore 3 = a (1) 

f(0) = 3 = a*b0  Therefore 3 = a (1)  f(1) = ab = 15 

f(0) = 3 = a*b0  Therefore 3 = a (1)  f(1) = ab = 15  3b =15 

f(0) = 3 = a*b0  Therefore 3 = a (1)  f(1) = ab = 15  3b =15  b =5 

f(0) = 3 = a*b0  Therefore 3 = a (1)  f(1) = ab = 15  3b =15  b =5  a =3 b =5 

f(0) = 3 = a*b0  Therefore 3 = a (1)  f(1) = ab = 15  3b =15  b =5  a =3 b =5  f(-2) = 3.5-2 = 3/25
