    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

    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
