Answer:
f(7) = 158
Explanation:
To evaluate f(7) substitute t = 7 into f(t)
f(7) = 3(7)² + 11 = (3 × 49) + 11 = 147 + 11 = 158
Answer: f(7) = 158
f(t)=3t^2+11 find f(7)...... this can be gotten by inputting the function of 't' into the given equation i.e.
f(t) = f(7)
t = 7, so therefore
f(7) = 3t² + 11
f(t) = 3(7)² + 11
= 3(49) + 11
= 147 + 11
