Evaluate the function rule for the given value f(x)=15x for x=3

f(3) = 45

Step-by-step explanation:

Substitute x = 3 into f(x) and evaluate

f(3) = 15 × 3 = 45

yes because there is exactly one y value for every x value

for function there can't be more than one value for every x value

26 is 33.33% of 78

step-by-step explanation:

26 is what percent of 78?

26 is p% of 78

equation: y = p% * x

solving our equation for p

p% = y/x

p% = 26/78

p = 0.3333

convert decimal to percent:

p% = 0.3333 * 100 = 33.33%
