Which function is a horizontal compression of its parent function f(x)=x^7 by a factor of 4? a - q(x)=(1/4 x)^7 b - r(x)=(4x)^7 c - s(x)=4x^7 d - t(x)=1/4 x^7 i think it’s b; check my answer

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
