Answer explanation

Follow order of operations. Exponents first.

f(2) indicates that x = 2

The exponent is x+1, so 2+1 = 3

The exponent is 3.

3³=3*3*3=27. Then multiply by 5.

Answer explanation

Follow order of operations. Exponents first.

h(-3) indicates that t = -3

The exponent is -3.

Remember, a negative exponent creates a fraction.

4^-3 or 1/64. Multiply by 3. Remember to multiply only to the numerator (top) of the fraction.
