Help pls Suppose f(x)=x^2 and k(x)=7x^2 which statement best compares the graph of k(x) with the graph of f(x)

A. The graph of k(x) is the graph of f(x) shifted 7 units right

B. The graph of k(x) is the graph of f(x) horizontally stretched by a factor of 7

c. The graph of k(x) is the graph of f(x) vertically stretched by a factor of 7

d. The graph of k(x) is the graph of f(x) vertically compressed by a factor of 7

The label on the car's antifreeze container claims to protect the car between ? 40°c and 125°c. to convert celsius temperature to fahrenheit temperature, the formula is c = 5 over 9 (f ? 32). write and solve the inequality to determine the fahrenheit temperature range at which this antifreeze protects the car. ? 40 > 5 over 9 (f ? 32) > 125; ? 40 > f > 257 ? 40 < 5 over 9 (f ? 32) < 125; ? 40 < f < 257 ? 40 < 5 over 9 (f ? 32); ? 40 < f 5 over 9 (f ? 32) < 125; f < 257
