If f(x)=(3×+7)^2, then f(1)=?
f(x) = (3x+7)^2f(1) = (3*1+7)^2 ... replace every x with 1f(1) = (3+7)^2f(1) = 10^2f(1) = 100Final Answer: 100
Start with f(x)=(3×+7)^2. Replace each instance of "x" with "1."Calculate the quantity inside parentheses first. Then, square that quantity. Label your result as "f(1)."
