Answer:

f(7) = 158

Step-by-step 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

Step-by-step explanation:

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

f(7) = 158
