Q. f(t)=80(4)tWhich of the following is an equivalent form of the function f in which the base of the exponent is 2 ?Choose 1 answer:(A) f(t)=80(2)2t(B) f(t)=80(2)t+2(C) f(t)=80(2)2t(D) f(t)=160(2)t
Understand Relationship: Understand the relationship between the bases 4 and 2. Since 4 is a power of 2, we can express 4 as 2 squared (4=22).
Substitute Expression: Substitute the expression for 4 in terms of 2 into the function.f(t)=80(4)t can be rewritten as f(t)=80(22)t.
Apply Power Rule: Apply the power of a power rule.According to the power of a power rule, (ab)c=a(b∗c). Therefore, f(t)=80(22)t becomes f(t)=80(22∗t).
Compare with Answer Choices: Compare the resulting expression with the answer choices.The expression f(t)=80(22t) matches with option (C) f(t)=80(2)2t.
