4. Which of the quadratic functions has the narrowest graph? A. y=-x^2

B. Y=1/6^2

C. Y=2x^2

D. y=1/8 x ^2

y=2x^2

Step-by-step explanation:

when you apply a number greater than 1 to the x value, it compresses the x value by the denominator of the fraction.

the inequality is:

250c+180g≥950

step-by-step explanation:

let c denotes the number of days in a week   miyoko worked as a cryptographer.

and g denotes the number of days in a week she works as a geologist.

now we are given that she earns $250 for every day she works as a cryptographer,and earns $180 for every day she works as a geologist.

now miyoko's goal is to earn more than $950 this week.

hence, the inequality could be represented as:

250c+180g≥950

i think the answer is b.

step-by-step explanation:

not 100% sure though.
